使用指针计算到三角形的点之间的距离

#include <iostream>
#include <cmath>

struct Point {
    double x;
    double y;
};

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() {
    Point A = {1.0, 2.0};
    Point B = {3.0, 4.0};
    Point C = {5.0, 6.0};

    double distance_AB = calculateDistance(&A, &B);
    double distance_BC = calculateDistance(&B, &C);
    double distance_CA = calculateDistance(&C, &A);

    std::cout << "Distance AB: " << distance_AB << std::endl;
    std::cout << "Distance BC: " << distance_BC << std::endl;
    std::cout << "Distance CA: " << distance_CA << std::endl;

    return 0;
}
