- Go.
- Next.
- C++.
- Next.
4. In the Project Title field, type calcMileage.
5. In Folder to create project in:, click ...
6. In Folder, click Make New folder and type calcMileage.
7. Click the calcMileage folder.
8. Click OK.
9. Click Next.
10. Click Finish.
11. Open the main.cpp file under Sources.
12. In the editor, type the following calcMileage application, using this template.
#include
using namespace std;
int main()
{
int miles;
int gallons;
float mpg;
cout << "Enter miles: ";
cin >> miles;
cout << "Enter gallons: ";
cin >> gallons;
mpg = miles / gallons;
cout << "Miles per gallon: " << mpg;
return 0;
}
13. Click Build, Build and Run.
14. Enter the number of miles.
15. Enter the number of gallons.
16. Observe the results.
17. Assignment Overview
18. For this assignment, you will write your first C++ application, called calcMileage. The goal of this program is to determine miles-per-gallon based on the number of miles driven and the number of gallons of gas you put in the tank. You will use the Code::Blocks software to write this application. Access this software via the Toolwire virtual desktop activity link in this unit.

29. Part 3: Describe the Application
30.
31. After running your application and observing the results, write a 1-2 page paper in which you complete the following:
32.
33. Define the variables in an application.
34. Define the expressions in an application.
35. Explain the data types in an application.
36. Discuss the cause of the inaccuracy in the original code and the approach used to fix the problem.
37. Ensure that your writing is professional and consistent with the standards and conventions of the IT community.
38.
39. Submit both the .cpp source code file and the Word document with the paper.

Assignment Overview
For this assignment, you will write a C++ application called calcPay for a financial company. The goal of this program is to determine gross pay for a 4-week pay period based on an hourly rate and the number of hours worked in each week of the pay period. Anyone working over 40 hours a given week earns time-and-a-half. You will use the Code::Blocks software to write this application. Access this software via the Toolwire virtual desktop activity link in this unit.
Assignment Instructions
Part 1: Write the Application
Write a C++ console application that asks the user to enter the hourly wage and number of hours worked for each week in a 4-week pay period. Create a custom function with appropriate input parameters and return type that calculates the total gross pay based on the values entered by the user. Use suitable loops for the user input and the processing of data entered by the user. The program should print out the gross pay for the pay period for the employee.
Part 2: Describe the Application
Write a 3-5-page paper in which you complete the following:
- Define and document the requirements for the calcPay application.
- Describe the stakeholders needed to help further define the application.
- Describe a collaboration plan for working with stakeholders.
- Analyze the behavior of basic, procedural-based programming constructs.
- Define the functions you have used in your application.
- Define the IF statements you have used in your application.
o Explain how the IF statements work.
Define the loops you used in your program.
o Explain how the loops work.
Explain how your application works and any issues you encountered with the application.
Include a screen shot of your application, using the Print Screen function, to show that your application works.
Submit both the source code file(s) and the Word document with the paper.
