Problem Solution:

#include<stdio.h>

int main(void){

long long int a,b,res,c,d;
int o;

while(scanf("%lld %lld",&a,&b)==2){

o=0;
res=0;

if(a==0 && b==0)break;

else{
        if(a<b){c=a;
        a=b;
        b=c;
     }

      while(a!=0){
       c=a%10;
       a=a/10;
       d=b%10;
       b=b/10;
       res=c+d+res;

      if(res>=10){o++;
               res=res/10;
                  }

       else res=0;
       }

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