Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

hello.cpp: In function `int main()':
hello.cpp:5: `cout' undeclared (first use this function)
hello.cpp:5: (Each undeclared identifier is reported only once for each
function it appears in.)
hello.cpp:5: `endl' undeclared (first use this function)
this is why #include <stdlib> does not work in C++. The latest restandardization of C++ has a part that pretty much says that all the include files are antiquated. That's why <iostream.h> is <iostream>. With that came the changing of C headers. In this case, #include <stdlib.h> becomes <cstdlib>. Don't ask why, I don't know =].
As for 'cout undeclared', that's also because of the most recent restandardization. If your studies of C++, you'll eventually read about namespaces. Namespaces are more or less your own way of scoping variables. All of the built in classes (cout, cin, endl, vector, string, etc.) are in the namespace std. So to use them you have to use :: operator since all those classes are no longer in a global scope. (Ah OOP.... i hate it sometimes)
