CSC 155Computer Science ILab 6 Student NameSection InstructorDue Date PROJECT Commission Function ApplicationObjectiveTo write, compile and execute a simple program that uses a function. PROJECT DESCRIPTIONCharles receives a salary of $2,500 per month. He also receives a 5% commission for sales over $15,000. Last month’s sales were $75,000. Write, compile and execute a program that uses a function to calculate Charles’ gross pay. Information About This ProjectThis project involves utilizing a decision / selection structures such as a block if-else statement. It also demonstrates the use of a function to perform calculations. Steps To Complete This ProjectSTEP 1Open MS Visual C++ and Write the Program CodeOpen Visual C++ on your computer. Write the program code that willallow the user to enter the necessary input items and then use these items to compute the required output value(s). Use the following instructions. Save your code in a file named:Commission. cppSTEP 2Open the Initial Program CodeFirst, type the code shown below, which consists of a preprocessing directive and a main() method.
