devc++爱心粒子代码

以下是Dev-C++实现爱心粒子效果的代码，需要先配置EGE绘图库：

#include <graphics.h>
#include <math.h>
#include <time.h>
#include <stdlib.h>

#define PI 3.14159265358979323846

int main()
{
    initgraph(640, 480);
    srand((unsigned)time(NULL));
    int x, y, r, g, b, i;
    double a, t;
    for (i = 0; i < 1000; i++)
    {
        x = rand() % 640;
        y = rand() % 480;
        r = rand() % 256;
        g = rand() % 256;
        b = rand() % 256;
        setlinecolor(RGB(r, g, b));
        for (a = 0; a < 2 * PI; a += 0.001)
        {
            t = pow(sin(a), 3) + pow(cos(a), 3);
            putpixel(x + 160 * t * t * sin(a), y - 130 * t * cos(a), RGB(r, g, b));
        }
    }
    getch();
    closegraph();
    return 0;
}
