2562.cpp

这些是我到目前在PKU上做出的题目

#include <iostream.h>

int main()
{
	int a,b,h,t,f;
	cin>>a>>b;
	while (a!=0 || b!=0)
	{
		t=0;f=0;
		while (a!=0 || b!=0)
		{
			h=(a%10)+(b%10)+f;
			a=a/10;b=b/10;
			if (h>=10)
			{
				t=t+1;
				f=1;
			}
			else
				f=0;
		}
		if (t==0)
			cout<<"No carry operation.\n";
		if (t==1)
			cout<<"1 carry operation.\n";
		if (t>1)
			cout<<t<<" carry operations.\n";
		cin>>a>>b;
	}
return 0;
}
