Why i am getting WA plz help anyone

Code: Select all

#include <set>
#include <map>
#include <list>
#include <cmath>
#include <ctime>
#include <queue>
#include <stack>
#include <cctype>
#include <cstdio>
#include <string.h>
#include <vector>
#include <cassert>
#include <cstdlib>
#include <cstring>
#include <sstream>
#include <iostream>
#include <algorithm>
#include <stdio.h>
using namespace std;

int main()
{
	 unsigned long int a,b,m,n,t;
	 int count=0;
	 while(1)
	 {
	      cin>>a>>b;
		  if(a==0&&b==0){ break;}
		  while(a%10!=0&&b%10!=0)
		  {
		  m=a%10,n=b%10;
		  t=m+n;
		  if(t>9)
		  {
				count++;
		  }
          a=a/10,b=b/10;
		  t=0;m=0,n=0;
		  }
		  if(count==0){ cout<<"No carry operation."<<endl; }
		  else if(count>0)
		  {
			   cout<<count<<" carry operation."<<endl;
		  }
		 count=0;
	  }
	 return 0;

}

The sample output has "3 carry operations." not "3 carry operation."

Why i am getting WA all test cases are show correct plz help.
give me some test case

Code: Select all

#include <set>
#include <map>
#include <list>

#include <ctime>
#include <queue>
#include <stack>
#include <cctype>

{
	 unsigned long int a,b,m,n,t;
	 int count=0;
	 while(cin>>a>>b)
	 {

		  if(a==0&&b==0){ break;}
		  while(a!=0&&b!=0)
		  {
		  m=a%10,n=b%10;

		  t=m+n;
		  if(t>=10)
		  {
				count++;
		  }
          a=a/10,b=b/10;
		  t=0;m=0,n=0;
		  }
		  if(count==0){ cout<<"No carry operation."<<endl; }
		  else if(count==1){cout<<count<<" carry operation."<<endl;}
		  else
		  {
			   cout<<count<<" carry operations."<<endl;
          }
		 count=0;
	  }
	 return 0;

}

Input:

Code: Select all

999 1
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.

Why I get wrong answer? I can not understand.[code#include<stdio.h>

1877803158 298799547
8 carry operations.

[brianfry713]

Try input:

Code: Select all

123 0
0 0

Output should be:

Code: Select all

No carry operation.

[brianfry713]

Try input:

Thanks brainfry. Seems like I wasnt handling buffer overflow correctly. BTW dont know why the post got deleted. My account also got deleted as well.
Anyways, much appreciate it.
