Hello all,

My C++ For Dummies book is an invaluable tool to me as I learn, but some of the things in there I don't understand. One of them is this line of code in every program:

using namespace std;

It is after library declarations...E.g.

#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;

"using namespace std;" includes sirten files that lets us call any function in the std namespace(the namespace std; files) without having to prefix it so "std::cout" can now be written "cout". Does this answer your question?

A man can be defined by what he does when no one is looking.
Science is only an educated theory, which we cannot disprove.
