下面是一个数字总和的程序。

#include<stdio.h>

int main()
{
    printf("\n\n\t\tStudytonight - Best place to learn\n\n\n");

    int n, sum = 0, c, remainder;

        printf("Enter the number you want to add digits of:  ");
        scanf("%d", &n);

    while(n != 0)
        {
            remainder = n%10;
            sum += remainder;
            n = n/10;
        }

        printf("\n\nSum of the digits of the entered number is  =  %d\n\n", sum);
        printf("\n\n\n\n\t\t\tCoding is Fun !\n\n\n");
        return 0;
}

输出:
