void Welcome();
{
    initgraph(1200, 800);

    playsound(TEXT("./fire/happy.mp3"),NULL,SND_LOOP|SND_FILENAME|SND_ASYNC)

    srand((unsigned int)time(NULL));

    settextstyle(80, 0, TEXT("仿宋"));

    while (!kbhit())
    {
        settextcolor(RGB(rand() % 150, rand() % 150, rand() % 150));
        outtextxy(300, 500, TEXT(" "));
        outtextxy(350, 550, TEXT(""));
