8/6     In C one can do "typedef int my_index_t;".  What's the equivalent in
        C#?  Thanks.
        \_ C#? Are you serious? Is this what the class of 2009 learn?
           \_ No.  I have to learn .NET code at work.  I am Class of '93.
           \_ python is what 2009 learns, see the motd thread about recent
              cal courses and languages
        \_ using directive.  I think you would have written:
           using my_index_t = int;
           Btw using is overloaded to do a few different things, so... enjoy
           the reserved word ambiguity created for your convenience. -mrauser
        \_ in C nobody can hear you scream
           \_ You're kidding me right? Java sucks donkeys, hands down.
              \_ HERESY.  You are dangerously close to THOUGHTCRIME, voter.
              \_ But Java haz eklipze!!! ZOMG!  HAT3R!!!!1!

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.

4/04    Is there a good way to diff 2 files that consist of columns of
        floating point numbers, such that it only tells me if there's a
        difference if the numbers on a given line differ by at least a given
        ratio?  Say, 1%?
        \_ Use Excel.

4/29    Why were C and Java designed to require "break;" statements for a
        "case" section to terminate rather than falling-through to the next
        section?  99% of the time poeple want a "case" section to terminate.
        In fact some compilers issue warning if there is no "break;" statement
        in a "case" section.  Why not just design the languages to have
        termination as the default behavior, and provide a "fallthru;"

7/19    In C or C++, how do I write the code of a function with variable
        number of parameters in order to pass the variable parameters to
        another function that also has variable number of parameters?  Thanks.
        \_ The usual way (works on gcc 3.0+, Visual Studio 2005+):
               #define foo(fmt, ...) printf(fmt, ##__VA_ARGS__)
           The cool new way (works on gcc 4.3+):

3/7     I have a C question.  I have the following source code in two identical
        files t.c and t.cpp:
                #include <stdlib.h>
                int main(int argc, char *argv[]) {
                  const char * const * p1;
                  const char * * p2;

2/4     random C programming/linker fu question.  If I have
        int main() { printf("%s is at this adddr %p\n", "strlen", strlen); }
        and soda's /proc/sys/kernel/randomize_va_space is 2 (eg; on)
        why is strlen (or any other libc fn) at the same address every time?
        \_ I don't pretend to actually know the right answer to this, but
           could it have something to do with shared libraries?

2/12    I need a way to make a really big C++ executable (~200MBs) that does
        nothing.  No static initialization either.  Any ideas?

        Java is #1!!! Followed by C, PHP, C++, Visual Basic, Perl,
        C#, Python, Javascript, then finally Ruby. The good news is
        Pascal is going waaaay back up!
        \_ C is still more popular than C++?  I feel much better about myself

7/20    For those who care btw, it looks like eclipse is now A Standard Tool
        at UCB ugrad cs, probably replaced emacs.  Furthermore, people get
        angry at seeing Makefiles, (since eclispe takes care of that).  I
        guess it's just a sign of the times.
        \_ The more people at my work use eclipse the less the code is
           managable in emacs.  I'm not sure which application's fault

Remarks The scope of a using directive is limited to the file in which it appears. Create a using alias to make it easier to qualify an identifier to a namespace or type. Create a using directive to use the types in a namespace without having to specify the namespace. A using directive does not give you access to any namespaces that are nested in the namespace you specify. Namespaces come in two categories: user-defined and system-defined. User-defined namespaces are namespaces defined in your code.
