Question

PKU上的1005题在c++上编译通过了为什么OJ上总是WA？求正确答案~

#include<iostream>
#include <math.h>
using namespace std;
#define PI 3.14

int main()
{
float x,y,z;
int n;
cin>>n;

for(int i=1;i<=n;i++)
{
cin>>x>>y;
z=(x*x+y*y)*PI/2/50;
z= ceil(z);
cout<<"Property "<<n<<": This property will begin eroding in year "<<z<<endl;
}
cout<<"END OF OUTPUT."<<endl;
}

Answer 1

ear "<<z<<en

c++我用的少, 不过印象中, 你这个地方不会按照题目要求的输出一个整数.

你可以先把它复制给一个int类型.

Answer 2

cout<<"Property "<<n<<": This property will begin eroding in year "<<z<<endl;
应该是cout<<"Property "<< i <<": This property will begin eroding in year "<<z<<endl;
应该是输出i 吧？不是输出n的。。。
