In the sample I/O it's "3 carry operations." not "3 carry operation.", you're missing the s at the end.

I did what u say,but still getting wa.......
#include<stdio.h>
#include<string.h>
int main()
{
int x,y,z,i,j,k,l;
char a[100],b[100],c;
while(scanf("%s %s",&a,&b)==2 && a[0]!='0' && b[0]!='0')
{
k=0;
l=0;
x=strlen(a);
y=strlen(b);

for(i=x,j=y;j>=0,i>=0;i--,j--)
{
z=(a-48)+(b[j]-48)+l;
if(z>9)
{
l=z/10;
k++;
}
}

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