Program Listing and Output

Lab Steps

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the iLab tab in Course Home.

Locate the Visual Studio 2010 icon and launch the application.

Lab:

Step 1: Requirements: An Address Database

Create a C++ console application that will store and retrieve names and addresses in a text file.

The program should do the following.

It should accept a series of names and addresses from the console. The user's input should be written to a text file in the CSV format described in the lecture, but do not include the field names in the first row of the file. Read the records from the text file, and display them in a user-friendly format. Provide a menu to allow the user to append records to the file, display the records, or exit the application.

Build upon the code below to complete the assignment.

//Specification: Append and display records in a address database

#include #include #include

using namespace std;

void menu(void); void writeData(void); void readData(void); string * split(string, char); const char FileName[] = "TestAddress.txt";

int main () { menu(); return 0; } //end main

void menu(void) { //allow user to choose to append records, display records or exit the program

}//end menu

void writeData(void){ //Write the Address Info to a file

}//end write data

void readData(void){ //read data from a file //use the split function to break a //deliminated line of text into fields

}//end read data

string * split(string theLine, char theDeliminator){ //Break theline into fields and save the fields to an array. //Each field will occupy one element in a character array. //theLine is a string with fields separated with theDeliminator character. //Assumes the last field in the string is terminated with a newline. //Useage: string *(lineBuffer, ','); //determine how many splits there will be so we can size our array int ; for(int ; i <theline.size();=""> if (theLine[i] == theDeliminator) splitCount++; } splitCount++; //add one more to the count because there is not an ending comma

//create an array to hold the fields string* theFieldArray; string[splitCount];

//split the string into seperate fields string ; int ; for(int ; i <theline.size();="" i++){="" read="" each="" character="" and="" look="" for="" the=""> if (theLine[i] != theDeliminator) { theField += theLine[i]; //build the field } else { //the deliminator was hit so save to the field to the array theFieldArray[commaCount] = theField; //save the field to the array ; commaCount++; } } theFieldArray[commaCount] = theField; //the last field is not marked with a comma... return theFieldArray; } //end split

Step 2: Processing Logic

Using the pseudocode below, write the code that will meet the requirements.

The pseudocode for the writeData function is shown below.

Start

open the text file to append

start do while loop

Allow user to enter name

store name (using getline method)

Allow user to enter city

store city (using getline method)

write name, city, etc. to the file

end loop

close the file

End

The program input should appear similar to this.

Append Records Name..........John Smith Street.........902 Union Ave City............Any Town State...........TX Zip Code......78552 "Enter another Record? (Y/N) "

The file structure should look like this.

John Smith, 902 Union Ave, Any Town, TX, 79552 Eric Jones, 345 State Way, Fresno, CA, 93432 ...

The file output should appear similar to the following.

Show Records __________________________________________ Record #1 Name...........John Smith Street..........902 Union Ave City.............Any Town State...........TX Zip Code......78552 __________________________________________ Record #2 Name...........Eric Jones Street..........345 State Way City.............Fresno State...........CA Zip Code.......93432 __________________________________________ (A)ppend Records, (S)how Records, (E)xit

Step 3: Create a New Project

Create a new project and name it LAB7. Write your code using the processing logic in Step 2. Make sure you save your program.

Step 4: Compile and Execute

a) Compile your program. Eliminate all the syntax errors.

b) Build your program and verify the results of the program. Make corrections to the program logic, if necessary, until the results of the program execution are what you expect.

Step 5: Print Screenshots and Program

Capture a screen print of your output. (Do a print screen and paste into an MS Word document.) Copy your code and paste it into the same MS Word document that contains the screen print of your output. Save the Word document as Lab07_LastName_FirstInitial.

Lab 4

Step 5: Program Listing and Output

Lab Steps

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the iLab tab in Course Home.

Locate the Visual Studio 2010 icon and launch the application.

Lab:

Step 1: Requirements: Phone-Dialing Program

Write a program that simulates the dialing of a phone number.

A user will input an 8-place number, for example: UN9-3177 (note that the hyphen is considered a digit).

The rules for entering phone numbers follow.

8 places It may have numbers, letters, or both. The phone number cannot begin with 555. The phone number cannot begin with 0. The hyphen must be in the 4th position. No other characters (@#$%^&*()_+=\|/><="" p="">

If all of the rules are met, you will output a message to the console that reads like the following. Phone Number Dialed: UN9-3177 *the number entered

If all of the rules are not met, then you output one of the following error messages to the console.

ERROR - Phone number cannot begin with 555 ERROR - Phone number cannot begin with 0 ERROR - Hyphen is not in the correct position ERROR - An invalid character was entered

It will then prompt the user to try again.

This should be a lot of fun!

Here are some great things to think about as you begin your program!

Define a function named ReadDials() that reads each digit and letter dialed into 8 separate char variables (DO NOT USE ARRAYS). All the digits are sent back through parameters by reference. Then, for each digit, the program will use a function named ToDigit(), which receives a single char argument (pass by reference) that may be a number or a letter of one of the digits dialed. If it is a number, then return 0 by value indicating that it is a valid digit. If the digit is a letter, then the number corresponding to the letter is returned by reference, and return 0 by value indicating that it is a valid digit. Here are the letters associated with each digit.

J K L

M N O

A B C

P Q R S

D E F

T U V

G H I

W X Y Z

If the digit entered is not one of the valid digits or one of the valid letters, return –1 by value indicating that you have an invalid digit.

A phone number never begins with a 0, so the program should flag an error if such a number is entered. Make ReadDials() return –2 in this case.

A phone number never begins with 555, so the program should flag an error if such a number is entered. Make ReadDials() return –3 in this case.

A phone number always has a hyphen (-) in the 4th position. Make ReadDials() return –4 in this case (if it doesn't have a hyphen in the 4th position). If a hyphen is in any other position, it is considered an invalid digit.

If the phone number is valid, the main calls the AcknowledgeCall function to write the converted number to the output file.

All the logic of the program should be put in functions that are called from Main(): ReadDials() and AcknowledgeCall().

The ToDigits() function is called from the ReadDials() function and is used to convert each letter entered individually into a digit and to verify that the user has entered a valid phone number. Have the program work for any number of phone numbers.

In the ToDigits() function uses the toupper function to convert any letters entered to uppercase. All the error messages are to be written to the output file from main() based on the return value from the functions.

Continue processing until the user enters a Q.

You will set up the 8 char variables to hold the digits of the phone number in main() and pass the variables to the functions by reference.

Sample Output from the Program

Enter a phone number (Q to quit): 213-2121

Phone Number Dialed: 213-2121

Enter a phone number (Q to quit): asc-dfer

Phone Number Dialed: 272-3337

Enter a phone number (Q to quit): 555-resw

ERROR - Phone number cannot begin with 555

Enter a phone number (Q to quit): 098-8765

ERROR - Phone number cannot begin with 0

Enter a phone number (Q to quit): 12345678

ERROR - Hyphen is not in the correct position

Enter a phone number (Q to quit): @34-*uyt

ERROR - An invalid character was entered

Enter a phone number (Q to quit): Q

Press any key to continue . . .

Step 2: Processing Logic

Using the pseudocode below, write the code that will meet the requirements.

Main Function Declare the char variables for the 8 digits of the phone number

while true Call the ReadDials function passing the 8 digits by reference. ReadDials returns an error code by value.

If the return value is -5, exit the do while loop

If the error code is -1, display the error message "ERROR - An invalid character was entered". If the error code is -2, display the error message "ERROR - Phone number cannot begin with 0". If the error code is -3, display the error message "ERROR - Phone number cannot begin with 555". If the error code is -4, display the error message "ERROR - Hyphen is not in the correct position". Otherwise, call the AcknowledgeCall function End-While

ReadDials function

Input the first digit If a Q was entered, return -5. Input the rest of the phone number

Call the ToDigit function for each of the 7 digits not for digit 4 If ToDigit returns -1, return -1 If digit 4 is not a hyphen, return -4. If digit 1 is 0, return -2. If digits 1 - 3 are 5, return -3 Otherwise, return 0

ToDigit function Convert the digit to upper case Use a switch statement to determine if the digit is valid and convert the letters to digits

If the digit is invalid, return -1. If the digit is valid, return 0.

AcknowledgeCall function Display the Phone Number.

Step 3: Create a New Project

Create a new project and name it LAB4.

Write your code using the processing logic in Step 2 (above). Make sure that you save your program.

Step 4: Compile and Execute

a) Compile your program. Eliminate all the syntax errors.

b) Build your program and verify the results of the program. Make corrections to the program logic, if necessary, until the results of the program execution are what you expect.

Step 5: Print Screen Shots and Program

Capture a screen print of your output (do a print screen and paste into an MS Word document). Copy your code and paste it into the same MS Word document that contains the screen print of your output. Save the Word document as Lab04_LastName_FirstInitial.

Lab 3

Step 6: Program Listing and Output

Lab Steps

Preparation:

If you are using the Citrix remote lab, follow the login instructions located on the iLab tab in Course Home.

Locate the Visual Studio 2010 icon and launch the application.

Lab:

Step 1: Requirements - DIVER Scoring Program

Your State Dive Association presently scores its diving competitions with pencil and paper. They would like for you to design and develop a Dive Program in C++.

The paper forms that they presently use have the following: Diver’s Name, City JudgeScore1 - The scores entered are from 0 to 10. JudgeScore2 JudgeScore3 JudgeScore4 JudgeScore5 DegreeOfDifficulty - This is assigned once for each diver. OverAllScore - The overall score is the individual diver’s scores totaled and then divided by the degree of difficulty. The highest and lowest scores are removed as they are often skewed entries. Total the three scores left, divide them by 3, and then multiply that by the DegreeOfDifficulty. The degree of difficulty ranges from 1.00 to 1.67. Display the diver's information and overall score.

When the competition is complete, there is a summary reportcreated that lists the total number of divers and the average of the overall scores.

Lab hints: When writing this lab, use nested loops. A nested loop is when one loop is completely contained in another loop. In an inner loop, you will read the five scores one at a time. Every time you read the score (in the loop), you will compare the score to the highest so far and also to the lowest so far so you can determine the highest and lowest scores, in addition to adding the scores up one at a time.

You also need to have your program process multiple divers. Put this in an outer loop. After you process the information for one diver, prompt the user if she/he wants to process another diver. Allow the user to type either a “Y” or “y” to enter another diver's information; otherwise, exit the loop. Write an event summary by calculating and displaying the average score for all divers and the total number of divers participating.

Garbage in Garbage Out (GIGO): The data being entered by the user needs to be validated. Scores by judges may range between 0 and 10. If the user enters an invalid score, display an error message, and prompt for the score again. Keep doing this until the user enters the score correctly. The degree of difficulty may range from 1.00 to 1.67.

Sample output from program

Lab 1 of 7: Getting Started (Your First C++ Programs) Lab Overview - Scenario/Summary

Welcome to Programming with C++. The purpose of this three-part lab is to walk you through the following tutorial to become familiar with the actions of compiling and executing a C++ program.

In general, this lab will instruct you on:

how to create a project; how to enter and save a program; how to compile and run a program; how to, given a simple problem using input and output, code and test a program that meets the specifications; and how to debug a simple program of any syntax and logic errors.Deliverables

Lab Steps

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the iLab tab in Course Home.

Lab:

Part A: Getting Started

Step 1: Start the Application

From the File menu, choose "New Project." Choose “Win32 Console Application.” Enter a name in the name field. Click “Next” and choose the following options: Application Type: "Console Application" Additional options: Check mark “Empty project” and uncheck 8. Click Finish. Your project is now created.

Step 2: How to Add a Source Code File to Your Project (.cpp file)

In the Solution Explorer, right-click on the “Source Files” folder and select "Add" and then "New Item." In the next dialog box, choose C++ file (.cpp), enter a name for your source code file, and press the Add button. Type or copy and paste your code into the newly created source code file. Build the file by pressing F7, and then execute your program by pressing CTRL-F5 (start without debugging) or use the F5 key (Start Debugging).

Step 3: Create a Source Code File

Now enter the following C++ program exactly as you see it. Use the tab where appropriate. [Note: C++ is case sensitive.] Instead of John Doe, type your name.

#include

using namespace std;

void main()

{

cout< "john="" doe"=""><endl;="">

cout< "cis170c="" -="" programming="" using="" c++\n";="">

cout< "\n\n\nhello,="" world!\n\n";="">

}

When you execute a program in debug mode (F5), the console screen may appear and disappear

before you have an opportunity to view your output. There are several techniques you can use to

pause the console screen so you can read the output. On the very last line in the main() function:

a. insert the statement: system("pause");

-OR-

b. insert an input statement: cin<myvarable;="">

Step 4: Output

The black screen or console should read:

John Doe

CIS170C - Programming using C++ Hello, World -

Step 5: Save Program

Save your program by clicking File on the menu bar and then clicking Save Program.cpp, or by clicking the Save button on the toolbar, or Ctrl + S.

Step 6: Build Solution

To compile the program, click Build on the menu bar and then click the BuildSolution or Build LabA option. You should receive no error messages. If you see some error messages, check the code above to make sure you didn't key in something wrong. Once you make your corrections to the code, go ahead and click Build >> Build Solution again.

Step 7: Execute the Program

Once you have no syntax errors, to execute or run your program, click Debug on the menu bar, and then click Start Without Debugging.

Step 8: Capture the Output

Print a picture of your screen output. (Do a print screen and paste this into MS Word.)

Step 9: Print the Source Code

Copy your source code and paste it into the same Word document as your screen print. Save the Word Document as Lab01A_LastName_FirstInitial

Note: Using the Visual Studio editor to compile your programs creates a lot of overhead. These additional files will become important as you create more sophisticated C# projects. Projects can contain one or more source-code files. For this course, you will not have to worry about all the extra files that are created.

End of Part A

Part B: Calculate Total Tickets

Step 1: Create New Project

Now create a new project and name it LAB1B. Make sure you close your previous program by clicking File >> Close Solution.

Step 2: Type in Program

Like before, enter the following program. Type in your name for Developer and current date for Date Written.

// ---------------------------------------------------------------

// Programming Assignment: LAB1B

// Developer: ______________________

// Date Written: ______________________

// Purpose: Ticket Calculation Program

// ---------------------------------------------------------------

#include

using namespace std;

void main()

{

intchildTkts, adultTkts, totalTkts;

;

+ adultTkts;

cout<totaltkts=""><endl;="">

}

Step 3: Save Program

Save your program by clicking File on the menu bar and then clicking Save Program.cpp, or by clicking the Save button on the toolbar, or Ctrl + S.

Step 4: Build Solution

To compile the program, click Build on the menu bar and then click the BuildSolution or Build LabB option. You should receive no error messages. If you see some error messages, check the code above to make sure you didn't key in something wrong. Once you make your corrections to the code, go ahead and click Build >> Build Solution again.

Step 5: Execute the Program

Once you have no syntax errors, to execute or run your program, click Debug on the menu bar, and then click Start Without Debugging.

Step 6: Capture the Output

Capture a screen print of your output. (Do a PRINT SCREEN and paste into an MS Word document.) Copy your code and paste it into the same MS Word document that contains the screen print of your output. 3. Save the Word Document as Lab01B_LastName_FirstInitial.

End of Part B

Part C: Payroll Program

Step 1: Create a New Project

Create a new project and name it LAB1C. Make sure you close your previous program by clicking File >> Close Solution.

Include a comment box like what you coded in Part B. This can go at the very top of your program.

Step 2: Processing Logic

You need to write a program that calculates and displays the take-home pay for a commissioned sales employee along with all of the deductions.

Input: Prompt the user for the weekly sales.

Process: Perform the calculations. The employee receives 7% of his or her total sales as his or her gross pay. His or her federal tax rate is 18%. He or she contributes 10% to his or her retirement program and 6% to Social Security.

Output: Display the results

Sample Output from Lab 1: Enter Weekly Sales: 28000

Total Sales: 28000.00 Gross pay (7%): 1960.00

Federal tax paid: 352.80 Social security paid: 117.60 Retirement contribution: 196.00 Total deductions: 666.40 Take home pay: 1293.60 Press any key to continue . . .

Flowchart: (continued on next page)

Pseudo Code:

1. Declare variables 2. Accept Input - weeklySales 3. Calculate Gross Sales * .07 4. Calculate Federal Pay * .18 5. Calculate Social Pay * .06 6. Calculate Pay * .1 7. Calculate Total Tax + Social Security + Retirement 8. Calculate Total Take Home Pay - Total Deductions 9. Display the following on separate lines and format variables with $ and decimal. a. Total Sales Amount: value of weekly sales b. Gross Pay (.07): value of gross pay c. Federal Tax paid (.18): value of federal tax d. Social Security paid (.06): value of social security e. Retirement contribution (.1): value of retirement f. Total Deductions: value of total deductions g. Take Home Pay: value of take home pay

Note: Use SetPrecisions(2) to format the output (see page 98 of the text). The statements should look something like the following:

//include the iomanip header file at the top of the file

#include

//use fixed and setprecision(2) to format the number

//use setw(8) to control the width of the field

//use \t to control the spacing between fields

cout< fixed=""><setprecision(2);="">

cout< "gross="" pay="" (0.07):\t="" $"=""><setw(8)=""><grosspay=""><endl;="">
