第一种：红色爱心代码
直接上代码：
#include#includeint 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 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--;}elsebreak;if (x < y){printf("o");y--;}elsebreak; if (x < y){printf("v");y--;}elsebreak; if (x < y){printf("e");y--;}elsebreak;}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--;}elsebreak;if (x < y){printf("o");y--;}elsebreak; if (x < y){printf("v");y--;}elsebreak; if (x < y){printf("e");y--;}elsebreak;}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
直接上代码

第四种：彩色闪动代码
直接上代码
#include #include #include #include int main(){for (float y = 1.5f; y > -1.5f; y -= 0.1f) {for (float x = -1.5f; x < 1.5f; x += 0.05f) {float a = x * x + y * y - 1;putchar(a * a * a - x * x * y * y * y <= 0.0f " />'*' : ' ');}putchar('\n');}for(;!kbhit();)//kbhit()位于conio.h中，检测是否有键按下{char str[10];sprintf(str,"color %x",rand() % 16); //形成一条color X的字符串，注意要用%xsystem(str);sleep(0.5);}return 0;}
第五种：文字填充代码
#define _CRT_SECURE_NO_WARNINGS#include #include #include #include #define I 20#define R 350 int main(){system("mode con cols=80lines=80");system("color F4");int i, j, e;int a;long time;for (i = 1, a = I; i < I / 2; i++, a--){for (j = (int)(I - sqrt(I*I - (a - i)*(a - i))); j > 0; j--)printf(" ");for (e = 1; e <= 2 * sqrt(I*I - (a - i)*(a - i)); e++)printf("\3");for (j = (int)(2 * (I - sqrt(I*I - (a - i)*(a - i)))); j > 0; j--)printf(" ");for (e = 1; e <= 2 * sqrt(I*I - (a - i)*(a - i)); e++)printf("\3");printf("\n");}for (i = 1; i < 49;i++){if (i == 20){printf(" 我喜欢你 ");i += 15;}printf("\3");}printf("\n");for (i = 1; i <= R / 2; i++){if (i % 2 || i % 3)continue;for (j = (int)(R - sqrt(R*R - i * i)); j > 0; j--)printf(" ");for (e = 1; e <= 2 * (sqrt(R*R - i * i) - (R - 2 * I)); e++)printf("\3");printf("\n");} system("pause");}
