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

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

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 npimport matplotlib.pyplot as pltt=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

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

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
