篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了双十一特辑爱心代码（程序员的浪漫）-李峋相关的知识，希望对你有一定的参考价值。
前言
最近《点燃我温暖你》中李峋的爱心代码超级火，看着特别心动，这不，光棍节快到了，给兄弟们教学一波爱心代码，赶在双十一前表白，让这个双十一不在是孤单一个人！
目录
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),字体色)
C语言简易爱心代码
原理
心形线直角坐标式（x^2+y^2-1）^3=x^2*y^3
让a=x^2+y^2-1，那么a*a*a就是（x^2+y^2-1）^3，有数学定理易得（x^2+y^2-1）^3<=x^2*y^3是为心形线里面的部分包括心形线，那么只要满足（x^2+y^2-1）^3<=x^2*y^3就输出某个指定符号，不满足就输出空格，就可以获得由这个字符组成的爱心，下面我使用的是'v'当指定字符，用三目运算符判断是否满足（x^2+y^2-1）^3<=x^2*y^3，注意输出完一行要换行。
代码
#include <stdio.h>
int main()
for (float y = 2.0f; y > -2.0f; y -= 0.1f)
for (float x = -2.0f; x < 2.0f; x += 0.05f)
float a = x * x + y * y - 1;
putchar(a * a * a - x * x * y * y * y <= 0.0f ? 'v' : ' ');
putchar('\\n');
执行结果

涉及知识点
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),字体色)
SetConsoleTextAttribute()是Windows系统中一个可以设置控制台窗口字体颜色和背景色的计算机函数，常用的几种颜色：
0=黑色 1=蓝色 2=绿色 4=红色 3=湖蓝色 5=紫色 6=黄色 7=白色 8=灰色
sheep()
执行挂起一段时间
代码
#include <stdio.h>
#include <math.h>
#include <windows.h>
#include <tchar.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()
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
0xc);//SetConsoleTextAttribute()是Windows系统中一个可以设置控制台窗口字体颜色和背景色的计算机函数
HANDLE o = GetStdHandle(STD_OUTPUT_HANDLE);// GetStdHandle()检索指定标准设备的句柄（标准输入、标准输出或标准错误）
_TCHAR buffer[25][80] = _T(' ') ;
_TCHAR ramp[] = _T("vvvvvvvv");
int count = 0;
int count1 = 0;
for (float t = 0.0f;; t += 0.1f)
int sy = 0;
float s = sinf(t);
float a = s * s * s * s * 0.2f;
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);
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)];
else
*p++ = ' ';
for (sy = 0; sy < 25; sy++)
COORD coord = 0, sy ;
SetConsoleCursorPosition(o, coord);//作用是设置控制台(cmd)光标位置
WriteConsole(o, buffer[sy], 79, NULL, 0);//从当前光标位置开始，将字符串写入控制台屏幕缓冲区
if (count <= 22)
printf("I Love You") ;//表白内容
printf(" To CSDN");// 被表白者的名字
count++;
else
printf("You Are My Best Lover.\\n");
count++;
if (count >= 44)
count = 0;
Sleep(36);//Sleep函数:执行挂起一段时间，也就是等待一段时间在继续执行
执行结果
Python简易爱心代码
准备工作
下载matplotlib软件包
涉及知识点
np.linspace()
用于返回指定区间等间隔的数组,例如np.linspace(0,2*np.pi)就是0到2π等间隔的数组
np.sin(
)
对中元素取正弦值
np.cos()
对中元素取余弦值
plt.plot()
是matplotlib.pyplot模块下的一个函数, 用于画图，它可以绘制点和线
plt.show()
展示图像
原理
原始的心形线的极坐标方程为r=a(1-cos)
与其对应的参数方程是：
x()=2r(sin-(sin2)/2)
y()= 2r(cos-(cos2)/2)，(0<=<=2π)
代码
import numpy as np
import matplotlib.pyplot as plt
t=np.linspace(0,2*np.pi)#用于返回指定区间等间隔的数组
x=2*1*(np.cos(t)-np.cos(2*t)/2)
y=2*1*(np.sin(t)-np.sin(2*t)/2)
plt.plot(y,x,c='purple')#c=''控制颜色
plt.show()执行结果
Python动态爱心代码
这个也是最还原的，代码过长，下面仅展示爱心的基础函数，需要的朋友可以去《点燃我温暖你》中李峋的同款爱心代码-Python文档类资源-CSDN文库下载，我设置的是免费下载
代码
x = 16 * (sin(t) ** 3)
y = -(13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t))执行结果
html动态爱心代码
代码
由于代码过长，源码放在资源html网页做的动态爱心（超好看）-Javascript文档类资源-CSDN文库里，可以免费下载
执行结果
真表白使用的（不懂编程也能学会）

</html>首先建一个txt文件
打开将代码粘进去并保存
找到 <!-- 在下面加名字 -->
<div id="name" style="color: blue;">这里加你想要加的文字</div>
如果你想要修改文字颜色的话，将上面的blue修改为你想要的颜色
然后保存退出，将文件名修改为表白.html,回车双击
如果修改完文件名还是代码就看看文件>查看>文件拓展名选了没
