Create a new file (in Dev C++) and save it as lab10_XYZ.cpp (replace XYZ with your initials). In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In Lab 7, you added some functionality for a main program loop and input validation. In this lab, you will create some general purpose functions to offload some of the tasks in main(). Write functions for: displaying a message (void) display menu and return user selection (int) prompt user for a number and return the number (int) adding (void) subtracting (void) multiplying (void) dividing (void) checking if number is 0 (bool) Prototypes must be written for each function. Definitions for each function may be in any order, after main(). Call functions as needed. Remember that functions can call other functions. If you see the same code repeating in different places, there is a good chance that a function could be used to simplify things. By now, you've gone through the thought process of how the main program loop works. Since the assignment is more about the use of functions, I'm providing a good bit of the main() function below. You will still need to determine arguments to use and how the parameters will be structured within each function. You may use the code below, or modify your existing code to use functions. SAMPLE MAIN PROGRAMint main(){bool flag = true;int choice;displayMessage("Hello, welcome to the calculator program!\n\n");while (flag){choice = menu();switch (choice){case ADD: add(); break;case SUB: subtract(); break;case MUL: multiply(); break;case DIV: divide(); break;case EX: flag = false; break;default: displayMessage("\nSorry, that was invalid\n"); break;}}displayMessage("\n\nProgram exiting. Goodbye!\n");return 0;} LANGUAGE IS C++ Simple as possible PLEASE!

Write functions for:

- prompt user for a number and return the number (int)
- adding (void)
- subtracting (void)
- multiplying (void)
- dividing (void)
- checking if number is 0 (bool)
