You should get a good introductory book on programming in standard C++.
Your code is not standard conformant and contains an error (that is what
the compiler already told you). It should read:
#include <iostream>
int main() {
std::cout << "hi, ...";
}

GCC (the GNU Compiler Collection) contains several frontends for different
programming languages (C, C++, Fortran etc.). The frontend for C++ is called
"g++". In order to compile/link C++ code, you should just use it:
$ g++ hi.cpp
This will produce a file called "a.out". In order to run it, type
$ ./a.out
hi, ...

Giving the -v switch to gcc/g++ on the command line usually prints such
useful information:
$ gcc -v
[...]
gcc version 3.3.3
