去年年底写的代码,有点意思

一些控制台函数

void windows_init()

    CursorInfo.bVisible = false;            //隐藏控制台光标
    SetConsoleCursorInfo(hOut, &CursorInfo);        //设置控制台光标状态

    srand(time(0));
}

void myprint(int y, int x, char colo,char color, const char* p)//
{
    COORD pos = { x,y };
    SetConsoleCursorPosition(hOut, pos);
    SetConsoleTextAttribute(hOut, colo+(color*0x10));
    printf(p);
}
char get_key()                    //获得按键键值
{
    char a;
    if (_kbhit() == 1)            //由于单使用 _getch()会导致程序堵塞,所以用先用_kbhit()获得是否有按键按下
    {
        a = _getch();
        return a;
    }
    return 0;

}

long HAL_GetTick()
{
    return clock();

}

void HAL_Delay(long a)
{
    long b;
    b = HAL_GetTick() + a;
    while (b> HAL_GetTick());

}
