got confused which specifier to use ?!
hello , there are some problems here !
first when i try to compile these codes i get negetive numbers while im supposed to get positive ones! i used different specifiers such as "%ld, %d , %i, %u ,and etc .and all i knew in order to check if one could give me a close answer! but no luck ...
the number i should get is sth like 1,475,365 or so , that according to my knowledge an unsigned long should give me that! or i can get such number with a "long" specifier ... any way when i try to use a long specifier i only get an irrelevant number of 136,465,321 or stuff like that ! well im using an ancient compiler name TC version 3 .. cause i need to program under dos and 16 bit based progs .. im tring on these .so a compiler like Tc can do the job for me ..but as you all know its only supports C90 standard! and i have difficulties using INT_MAX and stuff like that ...
please help me on this
and the second problem is that ..when i palce the whole structure above the "main() function " in order to use other functions to organize the whole program ... it just wont run ! it compiles without any problem ! but when i press "Enter" to start the program it just exits ! why ? !! is there any way to use functions ?
(if you notice you will see i commented a function that used to call FAT infos to be printed on screen ! thats why i commented it ! )
well, ill be really very happy if you help me n this
thanx in advance and i appreciate your kind help

/* Using Structure to hold data+Floppy disk stats
Original code :A Piece of COde that extracts floppy disk geometry information,
its been writen in pure C and has been tested and ran seccessfully under TC 3 ...
Added session:Floppy Disk Stat reader!, it is intended to show the floppy
-disk information rather than its FAT info or floppy geometry!
