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'); 	} }

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(\theta)

对中\theta元素取正弦值 

np.cos(\theta)

对中\theta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\theta)

与其对应的参数方程是:

x(\theta)=2r(sin\theta-(sin2\theta)/2)

y(\theta)= 2r(cos\theta-(cos2\theta)/2),(0<=\theta<=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()

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))

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
