show ( int ( *q )[4], int row, int col )
{

اين برنامه زيرمجموعه های يک مجموعه را به شما نشان می دهد. روش کارش هم اينجوريه که اول بايد تعداد اعضای مجموعه را مشخص کنيد .
بعدش هم اعضای مجموعه رو يکی يکی وارد کنيد .
بعد از زدن اينتر زير مجموعه ها مشخص می شوند .

ماشین حساب گرافیکی که جمع و ضرب و تفریق اعداد تا 128 رقم رو میتونه خیلی سریع حساب کنه ( ماشین حساب ویندوز تا 32 رقم اجازه میده ) .
کد این برنامه رو به صورت خیلی ساده و با استفاده از آرایه ها نوشتم. از تابع ضرب اون برای حساب کردن فاکتوریل اعداد بزرگ نیز میشه استفاده کرد. و برای قسمت گرافیکی آن به ناچار از Turbo C++ 3.0 استفاده کردم.
