C Program to print the sum of n odd and even numbers within range using for

Program

#include<stdio.h>
void main()
{
    int i;
    int start_range, end_range;
    int o_sum = 0;
    int e_sum = 0;
    printf("Enter the starting range:\t");
    scanf("%d", &start_range);
    printf("Enter the ending range:\t");
    scanf("%d", &end_range);
    for (i = start_range; i <= end_range; i++)
        if (i % 2 != 0)
        {
            o_sum = o_sum + i;
        }
        else
        {
            e_sum = e_sum + i;
        }
    printf("sum of all odd numbers in the given range is: %d\n", o_sum);
    printf("sum of all even numbers in the given range is: %d\n", e_sum);
}

Output

$ gcc sum-of-n-odd-and-even-numbers-within-range-using-for.c 
$ ./a.out
Enter the starting range:       25
Enter the ending range: 50
sum of all odd numbers in the given range is: 481
sum of all even numbers in the given range is: 494
