0 0

Correct output:

Code: Select all

3 carry operations.

I got WA more than 7 times in this problem and could not find the bug..
my code

Code: Select all

#include<stdio.h>
int main()
{
    long int num1,num2,x,y,carry,crry=0;
    while(scanf(" %ld %ld",&num1,&num2)==2 && (num1!=0 || num2!=0))
    {
        carry=0;

        while(num1!=0 || num2!=0)
        {
            x=num1%10;
            y=num2%10;
            num1=num1/10;
            num2=num2/10;
            if(x+y+crry>=10)
            {carry++;
            crry=1;



            }
            else
            crry=0;

        }
        if(carry==0)
        printf("No carry operation.\n");
        else if(carry==1)
        printf("1 carry operation.\n");
        else
        printf("%ld carry operations.\n",carry);



    }



    return 0;
}

Thank You..

Try running your code on the sample input.
