Assignment 10: Averaging numbers

due Thursday 3/7

Write a function average that has three numbers as its input values, and returns the average of those three numbers.

Also write a main program that allows the user to enter three numbers and find out their average. The computation must be done in the average function, but the input and output should still occur in the main part of the program. In other words, main should not include any arithmetic, and average should not contain any cin or cout statements.

Extensions

• Rewrite your average function to have five input numbers instead of three.
• Write a function median that takes five input numbers and returns the median of those numbers. For example, median(3.5,1.2,6.0,4.3,5.5) would have a return value of 4.3, the middle value out of the five inputs.
• Write a main program that allows the user to type five numbers, then displays both their average and their median.
