Answer in C Code ONLY please (No C++)

Use : Conditional branching structure (if-then-else statements)

and Loop structures

Relevant Programming Concepts: Conditional branching structures (if-then-else statements) Loop structures Problem 1: Develop a C program that computes the alternating sum of all positive integer numbers from 1 to n that are divisible by 9 in the following way. If the number is odd it is added to the sum, else it is subtracted from the sum. Sample Output: Enter the value of n: 100 The alternating sum of all positive numbers less than 100 divisible by 9 is: 54
