用easyx写抗锯齿了的有表盘的时钟

非常感谢您的提问！以下是用easyx写抗锯齿了的有表盘的时钟的代码：

#include <graphics.h>
#include <time.h>
#include <math.h>

#define PI 3.14159265358979323846

int main()

    // 设置字体
    LOGFONT font;
    ZeroMemory(&font, sizeof(font));
    font.lfHeight = 24;
    font.lfWeight = FW_BOLD;
    _tcscpy_s(font.lfFaceName, _T("微软雅黑"));
    HFONT hFont = CreateFontIndirect(&font);
    SelectObject(GetImageHDC(), hFont);

    // 获取当前时间
    time_t t = time(NULL);
    struct tm* tm = localtime(&t);

    while (true)
    {
        // 获取当前时间
        t = time(NULL);
        tm = localtime(&t);

        // 清空画布
        setbkcolor(WHITE);

        double angle = (tm->tm_hour % 12 + tm->tm_min / 60.0) * PI / 6;
        int x = 320 + 100 * sin(angle);
        int y = 240 - 100 * cos(angle);
        line(320, 240, x, y);

        setlinecolor(BLACK);
        setlinestyle(PS_SOLID, 4);

        settextcolor(BLACK);

            TCHAR str[3];
            _stprintf_s(str, _T("%d"), i);
            outtextxy(x - 10, y - 12, str);
        }

        // 刷新画面
        Sleep(1000);
        flushbatchdraw();
