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

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

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(' ') };

}
}
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
}
}

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

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 -->
