模拟时钟程序可以通过多种编程语言实现,包括C语言、Python、Java等。下面我将分别提供C语言、Python和Java的模拟时钟程序示例代码。
C语言实现
```c
include include include include define PI 3.14159265358979323846 void init_screen(int x0, int y0, int r0); void draw_clock_face(int x0, int y0, int r0); void draw_hands(int x0, int y0, int r0); void sec(); int main() { int x0 = 320, y0 = 240, r0 = 150; init_screen(x0, y0, r0); sec(); getch(); // 等待用户按键 closegraph(); // 关闭图形模式 return 0; } void init_screen(int x0, int y0, int r0) { int i, x, y, graphdriver, graphmode; char s; float alpha, a0 = PI / 2; graphdriver = DETECT; initgraph(&graphdriver, &graphmode, ""); setbkcolor(3); setcolor(2); circle(x0, y0, r0); // 内圆 circle(x0, y0, r0 + 30); // 外圆 setfillstyle(SOLID_FILL, 10); floodfill(x0 - r0 - 10, y0, 2); // 填写时钟数字 for (i = 1; i <= 12; i++) { sprintf(s, "%d", i); setcolor(i); textout(x0, y0, s); } } void draw_clock_face(int x0, int y0, int r0) { int i; float angle; for (i = 0; i < 360; i += 30) { angle = i * PI / 180; line(x0 + r0 * cos(angle), y0 + r0 * sin(angle), x0 + r0 * cos(angle + PI / 6), y0 + r0 * sin(angle + PI / 6)); } } void draw_hands(int x0, int y0, int r0) { int i; float angle, x, y; float hour_angle = (fmod(time(NULL), 43200) / 3600) * 360; float minute_angle = (fmod(time(NULL), 60) * 6) / 360; float second_angle = (fmod(time(NULL), 60) * 6) / 360; // 时针 x = x0 + r0 * cos(hour_angle); y = y0 + r0 * sin(hour_angle); line(x0, y0, x, y); // 分针 x = x0 + r0 * cos(minute_angle); y = y0 + r0 * sin(minute_angle); line(x0, y0, x, y); // 秒针 x = x0 + r0 * cos(second_angle); y = y0 + r0 * sin(second_angle); line(x0, y0, x, y); } void sec() { while (1) { cleardevice(); draw_clock_face(320, 240, 150); draw_hands(320, 240, 150); Sleep(1000); // 暂停1秒 } } ``` Python实现
