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();
}
}
```
