Error on C++'s Hello World - c++

Question

I started learning C++ and I tried to run the classic Hello World program:
#include <iostream>
using namespace std;
int main ()
{
cout << "Hello, World!";
return 0;
}
but when I compile it in terminal using GCC I always get that error:
Undefined symbols for architecture x86_64:
"std::basic_string<char, std::char_traits<char>, std::allocator<char> >::size() const", referenced from:

can you tell me why?

Answer 1

You've compiled your program with gcc, which is a C compiler, not a C++ compiler. Use g++ instead; it knows to include the C++ run-time libraries, where those missing symbols are defined.

Answer 2

Thats a C compiler you need to use a C++ compiler like rob says above g++. Also if you are a beginner I would highly recommend using Microsoft visual studio express if you run a windows OS; if not then netbeans.
