Write a C program segment that computes 1 + 2 + 3+...+(n-1) + n, where n is a positive integer value greater than 1. Assume that you enter an integer, but make sure that you validate that it is a positive integer that is greater than 1. Follow the loop body with an if statement that compares n(n+1) this value to and displays a message that indicates whether the values are the same or different. What message do you think will be displayed? 2 Following are two sample runs: Sample Run 1: Enter an integer value greater than 1 : 5 sum of numbers from 1 to 5 = 15 Sample Run 2: Enter an integer value greater than 1 : 0 Wrong input try again Enter an integer value greater than 1 : -5 Wrong input try again Enter an integer value greater than 1 : 1 Wrong input try again Enter an integer value greater than 1 20 sum of numbers from 1 to 20 = 210
