C program to calculate Total  of all digits using recursion : 

In this C program, we are going to learn how to sum of all digits using recursion method? Here, a number will be entered through the user and program will calculate sum of all digits.

Given a number and we have to sum of all digits using C language recursion function in C language.

Required knowledge  

• for loop in c program  just click 

Example:

    Input number:1251
    Output:
    Sum of total digits: 9

Sum of digits of a number program using recursion code : .

#include<stdio.h>

int digitecount(int num)

{

    static int first=0;

    if(num!=0)

    {

        first=first+(num%10);

        digitecount(num/10);

    }

    else

        return first;

}

int main()

{

    int n,bb;

    printf("Ente the number ");

    scanf("%d",&n);

    bb=digitecount(n);

    printf("sum of Total digits are  = %d",bb);

    return 0;

}

Output
