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=0double 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 << "*";elsecout << " ";}cout << endl;}cin.get();return 0;
}
