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;

12/8    c++ question, how do I overload << in my class so it will handle
        endl? ie: myclass << "some string" << endl
        I know how to do the "some string" part:
                myclass & operator << (const char * s);
        what about endl?

7/13    how do i pass variables to the system in C ?  e.g.

9/23    let's say there's a C library you want to use called libmdn.so.
        I think to load it you'd go something like:

3/16    Why does so much C sample code use #define instead of const?
        \_ because any good C code will use a bunch of preprocessor
           anyways. you can't be a good C programmer and eschew the
           preprocessor. For that, you need a language which fills those
           gaps with other constructs (c++ templates go a long way to
           obviate the need for preprocessor for example). you

6/20    I have a variable inside a struct.  I want to be able to initialize
        that variable ONCE and not write to it again.  Any subsequent writes
        should not be permitted.  Is there a way to do that in C?  I know
        about "const int foo = 5;" but the value I need to pass in is dynamic
        and happens at runtime.  Declaring a variable as const doesn't let
        me assign anything to it at all.  Thanks.
