Project Instructions Modify your code from Project 2 to make it modular. Instead of having one long main function that contains all the statements necessary to solve the problem given in previous projects, you must write several small functions that each solve a specific part of the problem. These small functions should then be executed in the correct order to implement a complete solution. The named constants you used in previous projects should now be made global so you won't have to pass those values to any function. In addition to the main function, your code must include the specified functions. These functions must be written exactly as specified to avoid a major error penalty. Make sure your program uses the values returned from your functions. Any functions that need input to perform a task will have to accept arguments. Global variables are prohibited. Steps: 1. Use the Divide and Conquer approach described in Section 6.1 of your textbook to modularize your program. 2. Make all of your named constants global. 3. Write the following functions: Function 1- mainMenu A void function that just displays the first menu when called. See Sample Run for format. Function 2 - streaming SerivceMenu A void function that just displays the streaming services when called. Function 3-distribution LabelMenu A void function that displays the distribution label types when called. Function 4-generateStreams A function that accepts the distribution label type and returns the number of streams generated based on the guidelines in Project 2.
Function 5- calculate Earnings A function that accepts the streaming service type and the number of streams and returns the amount of money earned from the song. Function 6- calculateLabelEarnings A function that accepts the distribution label type and the amount earned from the total songs streamed and then returns the amount the distribution label earned. NOTE: All functions must be coded as instructed above. Modifying the functions (meaning adding or removing parameters, changing the return type of the function, etc...) will count as a major error (i.e., one major error deduction for each function that is modified.) 4. Save your .cpp file using the required naming format as lastName Project3.cpp (where lastName is your last name i.e. jones Project3.cpp). 5. Click the assignment link to upload your file.
