Question

I'm not sure how to write this program using functions.  I'm also having trouble opening/reading files or writing values to files on a c drive. 

 

Program is written in C++.

HW_7a-1b 1. Write a program that asks the user to enter several integer values. The user can enter many numbers, and can stop by entering -999 (See output) 2. Use a do – while loop to read in the numbers. With each iteration (loop) one number is entered by the user. - If the number is an even number, it is written to a file. (only if it is an even number.) 3. Create a folder on your C: drive named: Numbers Inside the folder, create a file named: evens.txt If you are using a MAC and don't have a C: drive, create the Numbers folder on your Desktop. /* Output Enter positive numbers (-999 to quit.) Enter a number: 3 6. Enter a number: Enter a number: 7 Enter a number: 9 Enter a number: 22 Enter a number: 543 Enter a number: 77 Enter a number: 2 Enter a number: -999 The even numbers have been written to a file. 4. When the user enters -999, the loop stops. 5. Then, include this output statement: The even numbers have been written to a file.
