Add two numbers without using Arithmetic Operators

#include<stdio.h>
#include<conio.h>
void add(int m,int n)
{
 printf("%d",printf("%*c%*c",m," ",n," "));
}
int main()
{
add(3,5);
getch();
}

General syntax:-

printf("%*d",width,char);

where width is substituted in place of * in %*d and char is printed the number of times the width.

Explanation:-

In the above program " " is first printed m times followed by n times.So printf will return total number of " " which is nothing but m+n.

Output:-

              8
