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!

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),字体色)
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。
- #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()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
执行挂起一段时间

- }
-

- SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),

- 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
- }

下载matplotlib软件包
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
对中θ元素取正弦值
对中θ元素取余弦值
是matplotlib.pyplot模块下的一个函数, 用于画图,它可以绘制点和线
展示图像
原始的心形线的极坐标方程为r=a(1-cosθ)
与其对应的参数方程是:
x(θ)=2r(sinθ-(sin2θ)/2)
y(θ)= 2r(cosθ-(cos2θ)/2),(0<=θ<=2π)
- 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()
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
- x = 16 * (sin(t) ** 3)
- y = -(13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t))
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

首先建一个txt文件
打开将代码粘进去并保存
找到
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
