前言

这个在大一的时候就想找了，然后后面是找到了一个，但是忘记出处了。我决定把可以找到的所有爱心给整理一下，为了实现“理科生的浪漫”！！！

C/C++

首先就是可以调节他输出字体的颜色，默认当然是输出白色的，通过写一个函数来封装实现。如果参数越界了就默认输出白色了。这个我是当成固定写法的，要我记的话我也记不住。

#include<windows.h>
void color(int x){if(x>=0&&x<=15)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),x);elseSetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),7);
}

源代码

#include<stdio.h>
#include<windows.h>
void color(int x){if(x>=0&&x<=15)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),x);elseSetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),7);
}
void main(){printf("“愿我喜欢的人也在喜欢我!”");color(1);              //控制输出字体的颜色double x,y,a;for(y=1.5;y>-1.5;y-=0.1214){   //设置参数for(x=-1.5;x<1.5;x+=0.05){a=x*x+y*y-1;           //爱心方程if(a*a*a-x*x*y*y*y<=0){printf("*");//爱心构成的符号Sleep(1);}elseprintf(" ");}printf("\n");}
}

这个也可以搞的花哨一点，弄一个五颜六色的，不同符号的输出。我这里颜色采用的组个递增的形式，当然也可以采用随机数啦，然后输出的非空白字符是采用随机数的形式，这里要排除不可以输出的字符，所有范围就缩小了，具体ASCII对应如下所示。

#include<time.h>void color(int x){if(x>=0&&x<=15)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),x);elseSetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),7);
}
void main(){srand((unsigned)time(NULL));//随机种子int countColor=0;  double x,y,a;for(y=1.5;y>-1.5;y-=0.1214){   //设置参数for(x=-1.5;x<1.5;x+=0.05){a=x*x+y*y-1;           //爱心方程if(a*a*a-x*x*y*y*y<=0){countColor++;		//记录当前输出的颜色countColor%=16;		//颜色范围取[0,15]color(countColor);	//控制输出字体的颜色int countChars=33+rand()%94;//排除无法输出的字符[33,126]putchar(countChars);	//爱心的构成符号Sleep(1);}elseprintf(" ");}printf("\n");}
}

既然是知道他爱心方程的公式了，用其他语言来写就比较简单理解了。

这里的话没有cwindows还是要写成windows.h。网上找是没有找到。

}

Java

调了一下循环的界限，变长了一点，这个输出我的是卡顿的输出，没有那个连续的感觉，这个的话如果要那种感觉可以延长一下休眠的时间。输出是用的System.out.print，System.out.println输出会默认换行的。

java中的睡眠操作（sleep）_java 睡眠_豫章君的博客-CSDN博客https://blog.csdn.net/weixin_43929852/article/details/109264525

\033 是 ANSI 转义序列的起始字符，用于告诉终端后面跟着的是 ANSI 控制码。
[30m 是设置字体颜色的 ANSI 控制码，其中 30 代表字体颜色，后面的 m 表示设置结束。在 ANSI 控制码中，30 - 37 分别表示黑、红、绿、黄、蓝、品红、青、白这 8 种常用的字体颜色，而 m 则表示控制码的结束。
+ "颜色" 即为需要输出的文本内容。

public class Color {public static void main(String[] args) {System.out.print("\033[30m"+"黑");System.out.print("\033[31m"+"红");System.out.print("\033[32m"+"绿");System.out.print("\033[33m"+"黄");System.out.print("\033[34m"+"蓝");System.out.print("\033[35m"+"品红");System.out.print("\033[36m"+"青");System.out.print("\033[37m"+"白");}
}

这个颜色我感觉还是怪怪的，我这里选择的是青色。

public class EquationOfLove {public static void main(String[] args) throws InterruptedException {double x, y, a;for (y = 1.5; y > -1.5; y -= 0.1314) {for (x = -1.5; x < 1.5; x += 0.05) {a = x * x + y * y - 1;           //爱心方程if (a * a * a - x * x * y * y * y <= 0) {System.out.print("\033[36m"+"*");//输出字符Thread.sleep(50);//睡眠} else {System.out.print(" ");//输出空格}}//换行System.out.println();}}
}

Python

本来想用for循环加range的，但是里面的参数只能为整数。然后就是他的print是自带换行效果的。

TypeError: 'float' object cannot be interpreted as an integer

本来也想用C和Java的方法来写，发现怎么都输出不了，放弃了-_-,就只能用之前的turtle来写了，网上找了一个，然后自己修改了一下。自己写当然要挑一个粉色的啦！！！


from turtle import *
#笔尖的宽度
pensize(3)
#画笔颜色
color('pink')
#将海龟笔尖提起
penup()
#开始坐标
goto(0,-100)
#将海龟笔尖落下
pendown()
#逆时针150度，默认向右水平
setheading(150)
#爱心填充颜色
fillcolor('pink')
#开始填充
begin_fill()
#向前移动
fd(50)
#左半爱心
circle(50*-3.745,45)
circle(50*-1.431,165)
#向左旋转120
left(120)
#右半爱心
circle(50*-1.431,165)
circle(50*-3.745,45)
fd(50)
#结束填充
end_fill()
# 隐藏turtle图形(箭头)
hideturtle()
#暂停程序，停止画笔绘制，但绘图窗体不关闭，直到用户关闭pythonTurtle图形化窗口为止
done()

这边就有更加炫酷的了。
