C++ Exercises 9

1) Write a complete program that loops through the following task:

• use any arbitrary file name to create your file
• ask the user to enter a number
• if the user enters a negative number then quit the loop
• output that number to a file; each number should be on its own line

2) Write a complete program that reads numbers from a file (any file name). It should continue reading numbers until there are no more numbers left to read. The program should then display how many numbers it read and what the average of the numbers is.
