C语言实现多彩的心
实现过程其实很简单
首先使用for循环绘制心形
代码语言：javascript复制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');
}然后使用for循环进行切换cmd窗口颜色就可以做到
代码语言：javascript复制for (time = 0; time < 99999999; time );
system("color b");完整代码如下：
代码语言：javascript复制#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#define I 20
#define R 340
#include <string.h>
int main()
{
char answer[10];
printf(" 自从遇见了你，就不停地想你n");
printf(" 编一个死循环n 让我们一直走，一直走。");
printf(" 如果你也愿意n 输入yes,你可以看到我的真心n");
scanf("%s", answer);
if (!(answer[0] == 'y' && answer[1] == 'e' && answer[2] == 's'))
{
printf("555 n");
return 0;
}
//首先使用for循环打印出心形
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');
}
//循环变色
long time;
for (;;)
{
system("color a");
for (time = 0; time < 99999999; time );
system("color b");
for (time = 0; time < 99999999; time );
system("color c");
for (time = 0; time < 99999999; time );
system("color d");
for (time = 0; time < 99999999; time );
system("color e");
for (time = 0; time < 99999999; time );
system("color f");
for (time = 0; time < 99999999; time );
system("color 0");
for (time = 0; time < 99999999; time );
system("color 1");
for (time = 0; time < 99999999; time );
system("color 2");
for (time = 0; time < 99999999; time );
system("color 3");
for (time = 0; time < 99999999; time );
system("color 4");
for (time = 0; time < 99999999; time );
system("color 5");
for (time = 0; time < 99999999; time );
system("color 6");
for (time = 0; time < 99999999; time );
system("color 7");
for (time = 0; time < 99999999; time );
system("color 8");
for (time = 0; time < 99999999; time );
system("color 9");
}
getchar();
return 0;
}效果如下：
如何让心跳动起来
一颗不会动的心怎么能显得足够真（zhuang）诚（B）呢？
让我们使用数学函数巧妙地让这颗心动起来。
完整代码如下：
代码语言：javascript复制#include <stdio.h>
#include <math.h>
#include <windows.h>
#include <tchar.h>
#include <stdlib.h>
#include <string.h>
float f(float x, float y, float z) {
float a = x * x 9.0f / 4.0f * y * y z * z - 1;
return a * a* a - x * x * z * z * z - 9.0f / 80.0f * y * y * z * z * z;
}
float h(float x, float z) {
for (float y = 1.0f; y >= 0.0f; y -= 0.001f)
if (f(x, y, z) <= 0.0f)
return y;
return 0.0f;
}
int main() {
HANDLE o = GetStdHandle(STD_OUTPUT_HANDLE);
_TCHAR buffer[25][80] = { _T(' ') };
_TCHAR ramp[] = _T(".:-= #%@"); //心 每层使用的字符
int is = 0;
for (float t = 0.0f;; t = 0.1f)
{
//两种颜色循环切换
is ;
if(is%2==0)system("color d");
else system("color c");
int sy = 0;
float s = sinf(t);
float a = s * s * s * s * 0.2f;
//生成当前心的形态
for (float z = 1.3f; z > -1.2f; z -= 0.1f)
{
_TCHAR* p = &buffer[sy ][0];
float tz = z * (1.2f - a);
for (float x = -1.5f; x < 1.5f; x = 0.05f) {
float tx = x * (1.2f a);
float v = f(tx, 0.0f, tz);
//如果是在心的范围中间 就计算对应的层
if (v <= 0.0f) {
float y0 = h(tx, tz);
float ny = 0.01f;
float nx = h(tx ny, tz) - y0;
float nz = h(tx, tz ny) - y0;
float nd = 1.0f / sqrtf(nx * nx ny * ny nz * nz);
float d = (nx ny - nz) * nd * 0.5f 0.5f;
*p = ramp[(int)(d * 5.0f)];
}
//如果不在直接添加空格
else
*p = ' ';
}
}
//将当前的心形打印出来 按行打印
for (sy = 0; sy < 25; sy ) {
COORD coord = { 0, sy };
SetConsoleCursorPosition(o, coord);
WriteConsole(o, buffer[sy], 79, NULL, 0);
//if(sy ==12 )printf("520");
}
Sleep(33);
}
}效果如下：
