* C Program to find Sum of Digits of a Number using Recursion
int sum (int a);
int num, result;
printf("Enter the number: ");
result = sum(num);
printf("Sum of digits in %d is %d\n", num, result);
int sum (int num)
if (num != 0)
return (num % 10 + sum (num / 10));
$ cc pgm25.c $ a.out Enter the number: 2345 Sum of digits in 2345 is 14
