用c语言编写爱心的代码是什么？

#include <stdio.h>

#include <math.h>

#include <stdio.h>

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;
