Find Sum of Digits of the Number using Recursive Function in C Programming
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | #include<stdio.h> int calsum(int num) { int rem, sum; if (num != 0) { rem = num % 10; sum = sum + rem; calsum(num / 10); } return sum; } int main() { int num, val; printf("\nEnter a number: "); scanf("%d", &num); val = calsum(num); printf("\nSum of the digits of %d is : %d", num, val); return 0; } |
Output :
1 2 | Enter a number: 123 Sum of the digits of 123 is : 6 |
