just wondering if the system(argument) function is compiler specific.
I am using Dev c++ 4.0 and i have used it in the following way
andsystem("pause")system("cls")
I cannot find them in two C reference libraries i have so i was just wondering.
Also what are the optional arguements or more acurately - parameters.
I think it is platform specific, since you're running system commands, and such commands differ from system to system.
The system function itself is completely portable in standard C. However, the string you pass it is not even close to portable. A good example is system ( "cls" ). This works fine on DOS and Windows systems, but fails on Linux and Unix systems. On those machines, you would need system ( "clear" ).
My best code is written with the delete key.

Specifically:
STANDARDS
The system() function conforms to ISO/IEC 9899:1990 (``ISO C89'') and is
expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
ISO C89 being the current most implemented verion of 'C'. As in, any conforming compiler has this function.
hi,
yes it is platform dependent. In DOS you can pass arguments like "cls" , "pause" , "dir..." , etc. If you are using UNIX environment then these commennds can be used - "clear", "more" , "ls ..." , etc.

Thanks for your answers guys. Where can i find the optional parameters to be given to the system function. Or what are they?

Your system's help files give available commands. For DOS and Windows, type help at the command prompt and you will get a nice little list.

for linux hit tab twice and read VERY VERY fast. :-)

if ur using Dev C++ then u have to pass the "clear" instead of "cls" and for "pause" i don't know the related unix argument bcoz Dev C++ is designed similar to GNU C Compiler(GCC).
ok....look into the command list of unix and dos which perform the similar task..

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
can some mod lock this thread???
