爱心代码--C语言特供（可直接复制，亲测有效）
情人节到了，作为一名程序员，我们拥有属于我们的浪漫。
这里我总结了几种常见的爱心代码，简单易上手。
一.这是一种最为常见的爱心代码
#include
#include
int main()
{
float x, y, a;
for (y = 1.5; y > -1.5; y -= 0.1)
{
for (x = -1.5; x < 1.5; x += 0.05)
{
a = x * x + y * y - 1;
putchar(a * a * a - x * x * y * y * y <= 0.0 ? '*' : ' ');
}
system("color 0c");
putchar('\n');
}
return 0;
} 
也许我们可以再加一丁点东西让它变的更加浪漫一些
#include
#include
int main()
{
float x, y, a;
char color;
while (1)
{
for (y = 1.5; y > -1.5; y -= 0.1)
{
for (x = -1.5; x < 1.5; x += 0.05)
{
a = x * x + y * y - 1;
putchar(a * a * a - x * x * y * y * y <= 0.0 ? '*' : ' ');
}
system("color 0c");
putchar('\n');
}
}
return 0;
} 
二.一个会跳动的爱心又有谁不爱呢？
#include
#include
#include
#include
float f(float x, float y, float z) {
float a = x * x + 9.0f / 4.0f * y * y + z * z - 1;
return a * a * a - x * x * z * z * z - 9.0f / 80.0f * y * y * z * z * z;
}
float h(float x, float z) {
for (float y = 1.0f; y >= 0.0f; y -= 0.001f)
if (f(x, y, z) <= 0.0f)
return y;
return 0.0f;
}
int main() {
HANDLE o = GetStdHandle(STD_OUTPUT_HANDLE);
_TCHAR buffer[25][80] = { _T(' ') };
_TCHAR ramp[] = _T(".:-=+*#%@");
for (float t = 0.0f;; t += 0.1f) {
int sy = 0;
float s = sinf(t);
float a = s * s * s * s * 0.2f;
for (float z = 1.3f; z > -1.2f; z -= 0.1f) {
_TCHAR* p = &buffer[sy++][0];
float tz = z * (1.2f - a);
for (float x = -1.5f; x < 1.5f; x += 0.05f) {
float tx = x * (1.2f + a);
float v = f(tx, 0.0f, tz);
if (v <= 0.0f) {
float y0 = h(tx, tz);
float ny = 0.01f;
float nx = h(tx + ny, tz) - y0;
float nz = h(tx, tz + ny) - y0;
float nd = 1.0f / sqrtf(nx * nx + ny * ny + nz * nz);
float d = (nx + ny - nz) * nd * 0.5f + 0.5f;
*p++ = ramp[(int)(d * 5.0f)];
}
else
*p++ = ' ';
}
}
for (sy = 0; sy < 25; sy++) {
COORD coord = { 0, sy };
SetConsoleCursorPosition(o, coord);
WriteConsole(o, buffer[sy], 79, NULL, 0);
}
Sleep(33);
}
} 
三.简单的love
#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--;
}
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;
} 
四.简单又明了
#include
#define V 4//设置心形放大倍数
#define list (4*V+3)//列数
#define row (3*V+3)//行数
void FindMainPoint(char line[row][list]);
void Connect(int r1, int r2, int l1, int l2, char line[row][list]);//r行l列
void Print(char line[row][list]);
void Finger(char point[17][20]);
int main(void)
{
char line[row][list];
char point[17][20];
FindMainPoint(line);
Print(line);
printf("\n\n");
Finger(point);
return 0;
}
//找到关键点
void FindMainPoint(char line[row][list])
{
int list_mid = (list + 1) / 2 - 1;
int list_left = (list + 1) / 4 - 1;
int list_left_right = list_left + 1;
int list_right = list_mid + list_left + 1;
int list_right_left = list_right - 1;
int row_above = 1 - 1;
int row_mid = row / 3 - 1;
int row_mid_below = row_mid + 1;
int row_below = row - 1;

line[row_mid_below][list - 1] = '*';//(15,5)
line[row_below][list_mid] = '*';//(8,12)
Connect(row_mid, row_above, 0, list_left, line);//(1,4)&&(4,1)
Connect(row_above, row_mid, list_left_right, list_mid, line);//(5,1)&&(8,4)
Connect(row_mid, row_above, list_mid, list_right_left, line);//(8,4)&&(11,1)
Connect(row_above, row_mid, list_right, list - 1, line);//(12,1)&&(15,4)
Connect(row_mid_below, row_below, 0, list_mid, line);//(1,5)&&(8,12)
Connect(row_below, row_mid_below, list_mid, list - 1, line);//(8,12)&&(15,5)
return;
}
//连接关键点
void Connect(int r1, int r2, int l1, int l2, char line[row][list])
{
int i, j;
if (r1 > r2)
{
for (i = r1, j = l1;i >= r2;i--, j++)
{
line[i][j] = '*';
}
}
else
{
for (i = r1, j = l1;i <= r2;i++, j++)
{
line[i][j] = '*';
}
}
return;
}
//打印爱心
void Print(char line[row][list])
{
int i, j;
for (i = 0;i < row;i++)
{
printf("\t\t\t\t\t\t");//将图形尽量居中，改变大小后，自行修改
for (j = 0;j < list;j++)
{
if (line[i][j] != '*')
{
printf(" ");
}
else
printf("*");
}
printf("\n");
}
}
//打印手指
void Finger(char point[17][20])
{
int i, j;
for (i = 0, j = 5;j <= 6;j++)
point[i][j] = '*';//
for (j = 4, i = 1;i <= 8;i++)

point[i][j] = '*';//

point[i][j] = '*';

for (j = 0;j < 20;j++)
{
if (point[i][j] != '*')
{
printf(" ");
}
else
printf("*");
}
printf("\n");
}
} 
五.好看又直接
#include
#include
#include
#include
#define I 20
#define R 350
int main()
{
system("mode con cols=80 lines=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");
}
