C++创建函数以获取两点之间的距离

#include <iostream>
#include <cmath>

// 定义一个结构体表示点的坐标
struct Point {
    double x;
    double y;
};

// 计算两点之间的距离
double calculateDistance(Point p1, Point p2) {
    double distance = sqrt(pow(p2.x - p1.x, 2) + pow(p2.y - p1.y, 2));
    return distance;
}

int main() {
    // 创建两个点对象
    Point point1, point2;
    
    // 设置点的坐标
    point1.x = 1.0;
    point1.y = 2.0;
    
    point2.x = 4.0;
    point2.y = 6.0;
    
    // 调用函数计算距离
    double distance = calculateDistance(point1, point2);
    
    // 输出结果
    std::cout << "两点之间的距离为：" << distance << std::endl;
    
    return 0;
}
