Hello,
A new post, and not sure if this is more a basic C++ question than
an Emacs question.
I notice that in my Emacs editor, I cannot write just "cin >>" as
input or "cout <<"
as output. The g++ compiler used in Emacs requires "std::cin >>" and/
or "std::cout <<"
for input and output. Note, this is a Terminal window running under
Mac OS X.
So, again, if this is more a C++ question, I apologize in advance.
If so, I will ask that community
this question. If not, any information is appreciated. Thanks.

This has absolutely nothing to do with emacs.
On the other this piece of code:
// my first program in C++
#include <iostream>
using namespace std;
int main ()
{
cout << "Hello World!";
return 0;
}
compiles fine with g++ hello.cpp -o hello
so I don't get you.

I guess that the original poster didn't have
using namespace std;
In that case, an ANSI-C++ compiler should require
std::cout .

There's no such thing as the ``g++ compiler used in Emacs''. Emacs
just invokes the compiler installed on your system.
So this problem is about g++ usage, not about Emacs.
