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.

1. From the File menu, choose New Project.
2. Choose Win32 Console Application.
3. Enter a name in the name field.
4. Click OK.
5. Click Next, and choose the following options.
6. Application Type: Console Application
7. Additional options: Check mark Empty project.
8. Click Finish. Your project is now created.

1. In the Solution Explorer, right-click on the Source Files folder and select Add and then New Item.
2. In the next dialog box, choose C++ file (.cpp), enter a name for your source code file, and press the Add button.
3. 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).

// Purpose:                                            Ticket Calculation Program

// —————————————————————

#include <iostream>

using namespace std;

void main()

{

cout << “John Doe ticket program\n”;

int childTkts, adultTkts, totalTkts;

cout << “Please enter the number of child tickets:”;

cin >> childTkts;

cout << “Please enter the number of adult tickets:”;

cin >> adultTkts;

totalTkts = childTkts + adultTkts;

cout << “The total tickets are: “<<totalTkts << endl;

}

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;

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.

This program has three errors.

// Date Written:                          ______________________

// Purpose:                                            Average Program

// —————————————————————

#include <iostream>

using namespace std;

void main()

{

cout << “Find the Average Program\n”;

double num1, num2, num3, average;

cout << “Please enter number 1: “;

cin >> num1;

cout << “Please enter number 2: ”

cin << num2;

cout << “Please enter number 3: “;

cin >> num3;

average = num1 + num2 + num3 / 3;

cout << “The average is:  ” << average << endl;

system(“pause”);

}

When you build the solution you will see the debugger. Double click on an error to locate the error. If it is a syntax error, the error will be listed in the error list. Some errors will be underlined in red. Once you fix the syntax errors, use the F11 (step into code) and F10 (step over code) commands to locate the logic error in the code.

2.     Copy your code and paste it into the same MS Word document that contains the screen print of your output.

3.     List all three errors.

4.     Save this in the same Word document as Part JA.

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

Input: Prompt the user for the number of adult tickets. Prompt the user for the number of child tickets.

Process: Perform the calculations. The adult tickets cost $10.00 and the child tickets cost $6.00. The theater keeps 20% of the gross box office profit, and the rest goes to the movie distributor.

Output: Display the results.

Sample Output from Lab 1:

Flowchart: (continued on next page)

Pseudo Code:

1.      Declare variables

2.     Accept Input – child tickets and adult tickets

3.     Calculate Child ticket total = child tickets* 6

4.     Calculate adult ticket total = adult tickets * 10

5.     Calculate gross profit = child ticket total + adult ticket total

6.     Calculate net profit = gross profit *0.2

7.     Calculate distributor amount = gross profit – net profit

8.     Display the following on separate lines and format variables with $ and decimal.

a.     Gross Profit        value of gross profit

b.     Net Profit           value of net profit

c.     Distributor Amount      value of distributor amount

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

#include <iomanip>

//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 Profit :\t $” << setw(8) << grossProfit << endl;
 

1.     Capture a screen print of your output. (Do a PRINT SCREEN and paste into an MS Word document.)

2.     Copy your code and paste it into the same MS Word document that contains the screen print of your output.

3.     Use the same Word document as Part A and B.
