第一种：红色爱心代码
直接上代码：
#include<stdio.h>#include<Windows.h>int main(){system(" color 0c");//设计程序颜色 printf("遇见你是一件很开心的事情,爱你哟！！！\n");//打印文字 float x,y,a;//定义变量x,y,a for(y=1.5f;y>-1;y-=0.1f){for(x=-1.5f;x<1.5f;x+=.05f){a=x*x+y*y-1;putchar(a*a*a-x*x*y*y*y<0.0f?'x':' ');}Sleep(150);//停顿函数（1.5秒钟） putchar('\n'); //换行 }return 0;}
第二种：字母爱心代码
直接上代码
#include <stdio.h> int main() { int i, j, k, n = 0, x = 0, y = 50; //爱心的头部没有规律，所以直接打印 printf("\n\n\n\n\n"); printf(" lovelove lovelove\n"); printf(" lovelovelove lovelovelove\n"); printf(" lovelovelovelove lovelovelovelove\n"); printf(" lovelovelovelovelove lovelovelovelovelove\n"); printf(" lovelovelovelovelovelo lovelovelovelovelovelo\n"); printf(" lovelovelovelovelovelove lovelovelovelovelovelov\n"); for (i = 0; i < 2; i++) { printf("lovelovelovelovelovelovelovelovelovelovelovelovelove\n"); } for(i=0;i<5;i++) //爱心的中间部分的上部分 { y = 50; y = y - i*2; n++; for (k = 0; k < n; k++) //在每一行的起始位置先打印空格 { printf(" "); } while(1) //空格后面打印love，但是要注意love即使没打印完，也要换行 { if (x < y) { printf("l"); y--; } else break; if (x < y) { printf("o"); y--; } else break; if (x < y) { printf("v"); y--; } else break; if (x < y) { printf("e"); y--; } else break; } printf("\n"); } //最下面的部分，具体内容同上，没和上一部分放一起是因为从这行开始多两个空格 for (i = 0,n=3; i < 10; i++) { y = 37; y = y - i * 4; n++; for (k = 0; k < n; k++) { printf(" "); } while (1) { if (x < y) { printf("l"); y--; } else break; if (x < y) { printf("o"); y--; } else break; if (x < y) { printf("v"); y--; } else break; if (x < y) { printf("e"); y--; } else break; } printf("\n"); } printf("\n\n\n\n\n\n\n\n\n\n\n\n"); return 0;}
第三种：动态爱心代码
