编程绘制星星的方法有多种,这里提供几种不同编程语言的示例代码:
使用Python的turtle库
```python
import turtle
def draw_star(n):
for i in range(n):
print(" " * (n - i - 1) + "*" * (2 * i + 1))
n = int(input("请输入星星行数:"))
draw_star(n)
```
使用Python和pygame库
```python
import pygame
import numpy as np
WIDTH, HEIGHT = 800, 600
pygame.init()
screen = pygame.display.set_mode((WIDTH, HEIGHT))
clock = pygame.time.Clock()
num_stars = 200
stars = np.random.rand(num_stars, 3)
stars[:, 0] *= WIDTH
stars[:, 1] *= HEIGHT
stars[:, 2] *= 5 z轴,用于模拟深度
def move_stars():
stars[:, 2] -= 0.1
stars[stars[:, 2] < 0, 2] = 5
def draw_stars():
for star in stars:
x, y, z = star
size = (5 - z) / 5 * 100 根据z坐标计算大小
pygame.draw.circle(screen, (255, 255, 255), (int(x), int(y)), size)
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
screen.fill((0, 0, 0))
draw_stars()
pygame.display.flip()
clock.tick(60)
pygame.quit()
```
使用Python的matplotlib库
```python
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
np.random.seed(42)
n_stars = 1000
x = np.random.uniform(-1, 1, n_stars)
y = np.random.uniform(-1, 1, n_stars)
z = np.random.uniform(-1, 1, n_stars)
sizes = np.random.uniform(10, 100, n_stars)
colors = np.random.uniform(0, 1, (n_stars, 3))
fig = plt.figure(figsize=(10, 8))
ax = fig.add_subplot(111, projection='3d')
scatter = ax.scatter(x, y, z, s=sizes, c=colors, marker='o')
plt.show()
```
使用C语言
```c
include
void draw_star(int num) {
for (int i = 1; i <= num; i++) {
for (int j = 1; j <= (num - i); j++) {
printf(" ");
}
for (int j = 1; j <= 2 * i - 1; j++) {
printf("*");
}
for (int j = 1; j <= (num - 1); j++) {
printf(" ");
}
printf("\n");
}
}
int main() {
int num;
printf("请输入星星行数: ");
scanf("%d", &num);
draw_star(num);
return 0;
}
```
这些代码示例分别使用Python的turtle库、pygame库和matplotlib库,以及C语言,展示了如何绘制星星图案。你可以根据自己的需求和编程环境选择合适的代码进行尝试。
