Implement a program that calculates the sum of all numbers from 1 to N where N > 1. For example: For 5 it would be 15: 5 + 4 + 3 + 2 + 1 = 15. In the main function, the program prompts the user for an integer. Validate the input repeatedly until a valid value is entered. The integer is passed as an argument to a function named sumUp The function sumUp calculates the sum of 1 to N and returns the result. Define proper parameters and proper return type for the function. In the main function, the program shows the result on the screen. Note: The program does not need to output the equation! Sample Run: Input: 4 Sum: 10
