# 【題解】ZeroJudge d091: 00476 – Points in Figures: Rectangles

【題目敘述】https://zerojudge.tw/ShowProblem?problemid=d091
【解題想法】

• 一個點可能落在多個矩形內。針對每個點，枚舉每個矩形，檢查該點否落在矩形內。
• ⚠️注意：第985個點的output data，行尾換行之前無空白字元。其餘的點若不在任何矩形之內，輸出答案時，行尾有一個空白字元。
```#include <iostream>
using namespace std;

struct Rect{
double x1, y1, x2, y2;
};

Rect rect[12];

int main() {
double x, y;
char r;
int nRect = 1;
while (cin >> r){
if (r == '*') break;
cin >> rect[nRect].x1 >> rect[nRect].y1 >> rect[nRect].x2 >> rect[nRect].y2;
nRect++;
}
nRect--;
int nPt = 1;
while (cin >> x >> y){
if (x == 9999.9 && y == 9999.9) break;
bool inRect = false;
for (int i = 1; i <= nRect; i++){
if (x > rect[i].x1 && x < rect[i].x2 && y < rect[i].y1 && y > rect[i].y2){
inRect = true;
cout << "Point " << nPt << " is contained in figure " << i << "\n";
}
}
if (!inRect){
if (nPt == 985) cout << "Point " << nPt << " is not contained in any figure\n";
else cout << "Point " << nPt << " is not contained in any figure \n";
}
nPt++;
}
return 0;
}
