/*
Summary: Arithmetic, variables and arrays.

Prompt the user for how many numbers they want to enter.
Load the numbers into an array or list.  (The numbers might be floating point.)
Print the numbers entered back to the user, followed by the average, median and sum.
Find the average value, the median value and the sum.
The average is the sum divided by the count of the numbers, the median is the value that occurs in the middle.
If we have an even count of numbers, such as 10, then the the median is the average of the two middle values.
For greater detail about finding the median see MathIsFun (Links to an external site.)Links to an external site..
Example Execution:
How many numbers do you want to enter? 10
Enter number 1: 22.1
Enter number 2: 4
Enter number 3: 41
Enter number 4: 14
Enter number 5: 24.2
Enter number 6: 19
Enter number 7: 25
Enter number 8: 46
Enter number 9: 79
Enter number 10: 9
You entered 22.1, 4, 41, 14, 24.2, 19, 25, 46, 79, 9.
The average is 28.33.
The median is 23.15.
The sum is 283.3.
