【题意简述】:计算两数相加,有多少个进位。
【分析】:很简单,不过还是要注意输出的细节。当进位为1时,输出的operation,没有s。
详见代码:
// 216K 0Ms
#include<iostream>
using namespace std;
int main()
{
int a,b;
while(cin>>a>>b)
{
if(a == 0&&b == 0) break; // 在这贡献了n次WA~,傻!
int ans = 0;
int tmp1,tmp2;
int sum = 0;
while(1)
{
tmp1 = a%10;
a /= 10;
tmp2 = b%10;
b /= 10;
sum = tmp1 + tmp2 + sum;
if(sum>=10)
{
ans++;
sum = 1;
}
else
sum = 0;
if(a == 0&&b == 0) break;
}
if(ans == 0)
cout<<"No carry operation."<<endl;
else if(ans == 1)
cout<<"1 carry operation."<<endl;
else
cout<<ans<<" carry operations." <<endl;
}
return 0;
