那我这个呢

#include <iostream.h>
void main(void)
{
	unsigned int a,b;
	int i;
	cin>>a>>b;
	while(a!=0&&b!=0)
	{
		int count=0,flag=0;
		for(i=1;i<=11;i++)
		{
			if(a==0&&b==0)
				break;
			if(flag==1)
				if((a%10+b%10+1)>=10)
				{
					++count;
					flag=1;
				}
				else
					flag=0;
			else
				if((a%10+b%10)>=10)
				{
					++count;
					flag=1;
				}
				else
					flag=0;
			a/=10;
			b/=10;
		}
		if(count==0)
			cout<<"No carry operation."<<endl;
		else
			if(count==1)
				cout<<count<<" carry operation."<<endl;
			else
				cout<<count<<" carry operations."<<endl;
		cin>>a>>b;
	}
}
