Python

使用 `turtle` 库绘制爱心:

```python

import turtle

def draw_heart():

penup()

goto(0, -100)

pendown()

color('red')

begin_fill()

setheading(150)

circle(200, 90)

left(90)

circle(200, 90)

end_fill()

hideturtle()

draw_heart()

turtle.done()

```

JavaScript

在 HTML5 Canvas 中绘制爱心:

```javascript

const canvas = document.getElementById('heartCanvas');

const ctx = canvas.getContext('2d');

ctx.beginPath();

ctx.moveTo(250, 260);

ctx.arc(150, 150, 100, 0, -180);

ctx.fillStyle = 'red';

ctx.fill();

ctx.closePath();

```

C语言

使用ASCII字符绘制心形:

```c

include

int main() {

int i, j, n = 100;

for (i = 0; i <= n; i++) {

for (j = 0; j < n - i; j++) {

printf(" ");

}

for (j = 1; j <= 2 * i - 1; j++) {

printf("*");

}

printf("\n");

}

for (i = n - 1; i >= 0; i--) {

for (j = 0; j < n - i; j++) {

printf(" ");

}

for (j = 1; j <= 2 * i - 1; j++) {

printf("*");

}

printf("\n");

}

return 0;

}

```

C语言(使用数学公式)

```c

include

int main() {

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

for (float x = -1.5; x < 1.5; x += 0.05) {

float a = x * x + y * y - 1;

if (a * a * a - x * x * y * y * y <= 0.0) {

putchar('@');

} else {

putchar(' ');

}

}

putchar('\n');

}

return 0;

}

```

Java

使用 `Graphics2D` 绘制静态爱心:

```java

import javax.swing.*;

import java.awt.*;

public class LoveHeart extends JFrame {

public LoveHeart() {

setSize(400, 400);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setLocationRelativeTo(null);

setVisible(true);

}

@Override

public void paint(Graphics g) {

Graphics2D g2d = (Graphics2D) g;

g2d.setColor(Color.RED);

int[] xPoints = {200, 250, 200, 150};

int[] yPoints = {150, 200, 250, 200};

int nPoints = 4;

g2d.fillPolygon(xPoints, yPoints, nPoints);

g2d.fillArc(150, 150, 100, 100, 0, -180);

}

public static void main(String[] args) {

new LoveHeart();

}

}

```
