五种C语言爱心代码加附赠红色玫瑰
最基础爱心
代码：
#include
int main()
{
int i, j, k, l, m;
char c=3; //ASCII码里面 3 就是一个字符小爱心
for (i=1; i<=5; i++) printf("\n"); //开头空出5行
for (i=1; i<=3; i++) { //前3行中间有空隙分开来写
for (j=1; j<=32-2*i; j++) printf(" "); //左边的空格，每下一行左边的空格比上一行少2个 //8*n-2*i
for (k=1; k<=4*i+1; k++) printf("%c", c);//输出左半部分字符小爱心
for (l=1; l<=13-4*i; l++) printf(" "); //中间的空格，每下一行的空格比上一行少4个
for (m=1; m<=4*i+1; m++) printf("%c", c);//输出右半部分字符小爱心
printf("\n"); //每一行输出完毕换行
}
for (i=1; i<=3; i++) { //下3行中间没有空格
for (j=1; j<=24+1; j++) printf(" "); //左边的空格 //8*(n-1)+1
for (k=1; k<=29; k++) printf("%c", c);//输出字符小爱心
printf("\n"); //每一行输出完毕换行
}
for (i=7; i>=1; i--) { //下7行
for (j=1; j<=40-2*i; j++) printf(" "); //左边的空格，每下一行左边的空格比上一行少2个//8*(n+1)-2*i
for (k=1; k<=4*i-1; k++) printf("%c", c);//每下一行的字符小爱心比上一行少4个（这个循环是i--）
printf("\n"); //每一行输出完毕换行
}
for (i=1; i<=39; i++) printf(" "); //最后一行左边的空格
printf("%c\n", c); //最后一个字符小爱心
for (i=1; i<=5; i++) printf("\n"); //最后空出5行
return 0;
}
love组成爱心
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");

}
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

{
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");

打印红色爱心
代码：
#include
#include
#include
int main()
{
system("color F4"); //控制面板的颜色，F4为红色
double x,y,a;
for(y=1.5;y>-1.5;y-=0.1214) //调好的参数，爱心形状，可以自行调参数，改变爱心的形状
{
for(x=-1.5;x<1.5;x+=0.05)

a=x*x+y*y-1;
if(a*a*a-x*x*y*y*y<=0) //爱心方程
{
printf("*");
Sleep(10); //Sleep调节速度，可以调节爱心打印的速度
}
else
printf(" ");
}
printf("\n");
}
return 0;
}
闪烁爱心

#include

for (float y = 1.5f; y > -1.5f; y -= 0.1f)

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%x
system(str);
