Is C under DOS and Unix same? If different how n if same how pls explain.
 

C under dos and unix have some differences
like C uses 64 bit register to store computed value..
where as Unix compiler uses 90 bit.. so u may get different results for same progam in floating point operations!
 

The main difference is that under Unix capital letters matter, but under DOS they don't
 

Dos lacks Unix system calls. That's probably the biggest difference.
 

i think c works in the way under Linux and DOS .. only the compilers matter in this regard.
 

Hi all,
Of course C langage under doc or linux is the same. It is a Standardized language so it remain the same.
The difference is in the compilation even if we use the same compiler for each platform we obtain the same result in execution but not same binary file.
64 bits, 32 bits Microprocessor is with relation with machine/hardware and which can support any type of OS like linux, Unix, Dos, Windows etc.
 

They are the same, if compilers follow ANSI-C specification.
