Write a program to find the sum, average, range of N non-zero positive integers. 

 

• This program asks user to enter the value of N. Here, N indicates the number of values
  or terms from which user wants to sum, average, and range. This program then ask user
  to enter each term or values.
   
• For example, suppose, a user entered N (number of value or term) as 4. Then the user
  entered the following four (4) values as: 20, 40, 60, and 80. So, the sum will be
  20+40+60+80=200. You need to enter each term/value using for loop. Now calculate
  the sum.
   
• For calculating range, you need to subtract smallest number from the largest number.
   
• Once you get the sum, you can simply divide sum by N; you will get the average value.
