普通的爱心图案

C语言代码：

#include "stdafx.h"

#include

#include

int main()

{

float y, x, a;

for (y = 1.5f;y > -1.5f;y -= 0.1f)

{

for (x = -1.5f;x < 1.5f;x += 0.05f)

{

a = x*x + y*y - 1;

putchar(a*a*a - x*x*y*y*y <= 0.0f ? '*' : ' ');

}

putchar('\n');

}

return 0;

}

int main()

{

float y, x, z,f;

for (y = 1.5f;y > -1.5f;y -= 0.1f)

{

for (x = -1.5f;x < 1.5f;x += 0.05f)

{

z = x*x + y*y - 1;

f = z*z*z - x*x*y*y*y;

putchar(f <= 0.0f ? ".:-=+*#%@"[(int)(f*-8.0f)] : ' ');

}

putchar('\n');

}

getchar();

return 0;

跳动的爱心动画需要你运行程序后才可以看到。
