在cpp中围绕原点旋转点？

#include <iostream>
#include <cmath>

struct Point {
    double x;
    double y;
};

Point rotatePoint(const Point& point, double angle) {
    Point rotatedPoint;
    double radian = angle * M_PI / 180.0; // 将角度转换为弧度

    rotatedPoint.x = point.x * cos(radian) - point.y * sin(radian);
    rotatedPoint.y = point.x * sin(radian) + point.y * cos(radian);

    return rotatedPoint;
}

int main() {
    Point originalPoint = {2.0, 3.0};
    double rotationAngle = 45.0;

    Point rotatedPoint = rotatePoint(originalPoint, rotationAngle);

    std::cout << "Original Point: (" << originalPoint.x << ", " << originalPoint.y << ")" << std::endl;
    std::cout << "Rotated Point: (" << rotatedPoint.x << ", " << rotatedPoint.y << ")" << std::endl;

    return 0;
}
