编程玫瑰花束的代码可以根据不同的编程语言和需求有多种实现方式。以下是几种不同编程语言实现玫瑰花束的示例代码:
1. Java 使用 AWT
```java
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class RoseBouquet extends JPanel {
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
int centerX = getWidth() / 2;
int centerY = getHeight() / 2;
// 绘制花束的绿色花茎
g.setColor(Color.GREEN);
g.fillRect(centerX - 5, centerY, 10, 200);
// 绘制花束的红色玫瑰花
g.setColor(Color.RED);
for (int i = 0; i < 8; i++) {
int angle = i * 45;
int x = (int) (centerX + Math.cos(Math.toRadians(angle)) * 80);
int y = (int) (centerY - Math.sin(Math.toRadians(angle)));
g.fillRect(x, y, 10, 10);
}
}
public static void main(String[] args) {
JFrame frame = new JFrame("Rose Bouquet");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new RoseBouquet());
frame.setSize(400, 400);
frame.setVisible(true);
}
}
```
2. Python 使用 turtle
```python
import turtle
def draw_flower():
turtle.speed(10)
turtle.bgcolor("black")
colors = ["red", "blue", "yellow", "green"]
for i in range(36):
turtle.color(colors[i % 4])
turtle.forward(100)
turtle.left(45)
turtle.forward(100)
turtle.left(135)
turtle.forward(100)
turtle.left(45)
turtle.forward(100)
turtle.left(175)
turtle.right(10)
turtle.hideturtle()
turtle.done()
draw_flower()
```
3. Python 使用 matplotlib 和 numpy 绘制玫瑰曲线
```python
import matplotlib.pyplot as plt
import numpy as np
def rose_curve(theta, k):
r = np.cos(k * theta)
return r
theta = np.linspace(0, 2 * np.pi, 1000)
k = 5
r = rose_curve(theta, k)
x = r * np.cos(theta)
y = r * np.sin(theta)
plt.figure(figsize=(6, 6))
plt.plot(x, y, 'r')
plt.axis('equal')
plt.title('A Rose in Python')
plt.show()
```
4. C 语言绘制玫瑰花
```c
include
int main() {
int i, j, n;
printf("请输入玫瑰花的大小(建议输入10-20之间的数):");
scanf("%d", &n);
for (i = -n / 2; i <= n / 2; i++) {
for (j = -n / 2; j <= n / 2; j++) {
if (i * i + j * j <= (n / 2) * (n / 2)) {
if ((i + j) % 2 == 0) {
printf(" ");
} else {
printf("
