I am supposed to explain/define “code space” as part of a homework problem in C++ but I couldn’t find much with Google.  Can someone explain it in lame terms?

Wiki is your friend http://en.wikipedia.org/wiki/Code_space

You will probably need to explain by example.  These are stored in code space: it is basically any code that cannot be changed while the program is running

const char* myname = "wo de ming zi";
int HowMany (int* x)
{
   int count;

   for (count = 0; x[count] != 0; ++count)
      ;
   return count;
}

These will be in data space

int x[50];
bool robert;

Codespace is increased when the routines appear in headers - every source file that includes the header has a copy of the routine.  This is a very common problem with coders who love inline code.  In the old days when space was limited, codespace was reused with overlays.  Nowadays, space isn't a problem and automatic paging takes care of it.
