Find sum of odd and even numbers from 1 to N

/* Write a C program to find the sum of odd numbers and *
* sum of even numbers from 1 to N. Output the computed *
* sums on two different lines with suitable headings   */

Output
RUN1

Enter the value of N
10
Sum of all odd numbers  = 25
Sum of all even numbers = 30

RUN2
Enter the value of N
50
