Sum of Digits Using Recursion in C

A simple program was written by my good friend and fellow software engineer Sir Ernel to sum of digits using recursion using C programming language.

Program Listing

#include<stdio.h>

int sumd(int x)

{

if(x==0)

return 0;

else

return (x%10)+sumd(x/10);

}

int main()

{

int a;

printf("Enter a number :");

scanf("%d",&a);

int b=sumd(a);

printf("\nSum of digits= %d",b);

getch();

}

Sum of Two Number Without Using Plus Symbol in C

A simple program was written by my good friend and fellow software engineer Sir Ernel to add the two numbers without using a plus symbol using a C programming language.

Program Listing

#include<stdio.h>

int main(){

int a,b,sum;

printf("Enter any two integers: ");

scanf("%d%d",&a,&b);

sum = a - ~b -1;

printf("Sum of two integers: %d",sum);

return 0;
