2014/1/14-2/5 [Computer/SW/Languages/C_Cplusplus] UID:54763 Activity:nil | 1/14 Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
C? I have some overloaded functtions where one takes an integer
parameter and the other a pointer parameter. When I call it with
"NULL", the compiler matches it with the integer version instead of
the pointer version which is a problem. Other funny effect is that
sizeof(NULL) is different from sizeof(myPtr). Thanks.

2009/2/28-3/11 [Computer/SW/Compilers] UID:52661 Activity:nil | 2/28 I'm looking for a recommendation of a compiler/IDE to use to
develop C/C++ code under Linux. In school, we used jove/gcc and
I still use emacs/vi and gcc to this day. However, it is really
lacking. Under Windows I tried Visual Studio and there were some
really nice things about it, although it was so overwhelming that
after 6 months of occasional use I still didn't really know what I

generator with a good seed (I just need random 18 bit
identifiers). The usual time(NULL) is OK, except my program
might be invoked faster than once a second, and seeding using
time() produced the same result. I tried clock() but it seems
to return 0. My program needs to be run in Linux/DOS (Watcom

Can I find this stuff out at compile time somehow?
\_ You aren't planning on running your code on any other processors?
\_ May I ask what it is you want to achieve ultimately? If you don't
know your architecture and want to find out dynamically, there are
tools that can peek/poke to give you definitive answers, plus you get

2008/4/2-6 [Computer/SW/Languages/C_Cplusplus] UID:49645 Activity:moderate | 4/2 Is there an interpreted version of C or C++ that can be used for
educational purposes? It doesn't have to be full-featured or
strictly adhere to the standards, but it's painful for students
to change a variable in a for loop and then wait for a compile
to see how it changes the result. Something really lightweight
would encourage them to play around a lot more and learn more in
