用visual studio 编写爱心

以下是用 C++ 语言在 Visual Studio 中编写爱心的代码：

#include <iostream>
#include <math.h>
#include <Windows.h>

using namespace std;

const int WIDTH = 80;
const int HEIGHT = 40;

int main()
{
    // 设置命令行窗口大小和缓冲区大小
    HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    SMALL_RECT rc = { 0, 0, WIDTH - 1, HEIGHT - 1 };
    SetConsoleWindowInfo(hOut, TRUE, &rc);
    COORD size = { WIDTH, HEIGHT };
    SetConsoleScreenBufferSize(hOut, size);

    // 清空屏幕
    system("cls");

    // 计算爱心曲线上的点坐标
    double x, y, z;
    for (double i = 0; i < 2 * M_PI; i += 0.05)
    {
        z = pow(sin(i), 2);
        x = 16 * pow(sin(i), 3);
        y = -(13 * cos(i) - 5 * cos(2 * i) - 2 * cos(3 * i) - cos(4 * i));
        int posX = (int)(x * 2) + WIDTH / 2;
        int posY = (int)(y * 2) + HEIGHT / 2 - 5;
        if (posX >= 0 && posX < WIDTH && posY >= 0 && posY < HEIGHT)
        {
            SetConsoleCursorPosition(hOut, { (SHORT)posX, (SHORT)posY });
            cout << "*";
        }
    }

    return 0;
}

运行程序后，会在命令行窗口中绘制出一个爱心图案。效果如下：

                   **

               **********
