[sunny]

make ur s[10][4] array double.

thank you,i edit and got AC

[Carunty]

I dont know why it is WA. Can anyone help me?
Here is my code.

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main(){
int c=1; double y,z; char x; vector<vector<double> > v;
while(cin >> x,x!='*'){
vector<double> w;
for(int i=0;i<4;cin>>y,w.push_back(y),++i);
v.push_back(w);
}
while(cin >> y >> z){
if(y==9999.9&&z==9999.9) break;
int i;
for(i=0;i<v.size();++i) if(v[0]<y&&y<v[2]&&v[1]>z&&z>v[3]) break;
if(i==v.size()) cout << "Point " << c << " is not contained in any figure" << endl;
else cout << "Point " << c << " is contained in figure " << i+1 << endl;
++c;
}
}

I don't know why I get so many WA on this easy question. I have read all the thread on Q476, but none of them solved my problem. Can anyone give me a hand ???

Every suggestion is appreciated !!!

Here's my code:

Search your problem in the forum first. If you find a thread use it. Otherwise open a new one.

[deadhunter411]

plz tell me where is the problem??

here is my c-code
thank you very much

Do not create a new thread if there is one already..

Sorry. I'm Taiwanese.so..
I don't know the "thread" means.
Can you explan it?
thank you very much!!

[helloneo]

I meant "new topic" by that..

[deadhunter411]

I meant "new topic" by that..

sorry..
I still can't understand how to solve the error...

new topic???
can you give me an example?

thank you..

[helloneo]

Hmm.. I didn't say about how to solve it..

Use old topics.. did you go to the link I mentioned above..?

thank you for help


struct testp point[200];
to
struct testp point[400000];

than get AC...
