RE: [PLUG] gcc vs cc vs c++

["Bradley Molnar" <brad-current@litech.org>]

thanks that clears it up.

For a moment, I thought that I had forgotten how to do c++.

To follow up on this, its the same compiler. Its just that when you 
invoke gcc as g++, as Kyle points out, it goes into C++ mode. You can 
use gcc as gcc if you specify the language and link with the appropriate 
librarys. For the simple example of:

#include <ostream.h>

int main()
{
   cout << "Hello, World" << endl;
   return 0;
}

You could compile this with either:

g++ foo.cpp

or

gcc -std=gnu++98 -lstdc++ foo.cpp

I'd recomnend not doing the latter. C++ is sufficiently complex that 
there are good reasons for g++ to exist.
