使用c++实现输出爱心（软件：visual Studio）

#include <iostream>
using namespace std;

int main()
{
    //爱心曲线方程(x^2+y^2-a)^3-x^2*y3=0
    double a = 0.5;
    //定义绘图边界
    double bound = 1.3 * sqrt(a);
    //x,y坐标变化步长
    double step = 0.05;

    //二维扫描所有点,外层逐层扫描
    for (double y = bound; y >= -bound; y -= step)
    {
        //内层逐点扫描
        for (double x = -bound; x <= bound; x += 0.5 * step)
        {
            double result = pow( (pow(x, 2) + pow(y, 2)-a), 3) - pow(x, 2) * pow(y, 3);
            if (result <= 0)
                cout << "*";
            else
                cout << " ";
        }
        cout << endl;
    }
    cin.get();

    return 0;
}
