用c++ 写一下判断钜形和圆重叠

好的，以下是C++代码实现判断矩形和圆形是否重叠：

#include <iostream>
#include <cmath>
using namespace std;

struct Point {
    double x, y;
};

bool isOverlap(Point center, double radius, Point rectCorner1, Point rectCorner2) {
    // 计算矩形中心点
    Point rectCenter;
    rectCenter.x = (rectCorner1.x + rectCorner2.x) / 2;
    rectCenter.y = (rectCorner1.y + rectCorner2.y) / 2;

    // 计算矩形宽度和高度
    double rectWidth = abs(rectCorner1.x - rectCorner2.x);
    double rectHeight = abs(rectCorner1.y - rectCorner2.y);

    // 计算圆心到矩形中心的距离
    double distance = sqrt(pow(center.x - rectCenter.x, 2) + pow(center.y - rectCenter.y, 2));

    // 判断是否重叠
    if (distance <= radius + sqrt(pow(rectWidth, 2) + pow(rectHeight, 2)) / 2) {
        return true;
    }
    else {
        return false;
    }
}

int main() {
    Point center = { 0, 0 };
    double radius = 2;
    Point rectCorner1 = { -1, -1 };
    Point rectCorner2 = { 1, 1 };

    if (isOverlap(center, radius, rectCorner1, rectCorner2)) {
        cout << "Circle and rectangle are overlapping." << endl;
    }
    else {
        cout << "Circle and rectangle are not overlapping." << endl;
    }

    return 0;
}

这里的 `isOverlap` 函数接收圆心和半径，以及矩形的两个对角点作为参数，返回是否重叠的布尔值。
