Couldn't compile the simple "Hello World"

So, this is my first C++ program under linux. My OS is Red Hat 8.0, and my codes are like following:

$vi hello.cpp

#include <iostream>
using namespace std;

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

$ g++ -o hello hello.cpp

the error message are:
hello.cpp: In function `int main()':
hello.cpp:4: `cout' undeclared (first use this function)
hello.cpp:4: (Each undeclared identifier is reported only once for each
function it appears in.)
hello.cpp:4: `endl' undeclared (first use this function)

It could run under M$ with VS 6.0. Can someone tell me what I did wrong here? Thanx.
