Old C++ book - Newer C++ tutorials

[FastDasher]

Hello, this is my first post and I've started to learn C++. I noticed that the book I'm using was published in 1995. Then I started looking at newer tutorials like the famous "Hello World" for beginners.

In the book the code is:

#include <iostream.h>
main () {
 cout << "The volume of the box car is ";
 coun << 11 * 9 * 40;
 coun << endl;
}

And on this website the code was:

#include <iostream>

int main()
{
    std::cout << "This is a native C++ program." << std::endl;
    return 0;
}

I'm beginning to notice differences with the past and current versions of C++. Or am I wrong, are these just different methods of programming in C++? Does it matter if I use an older book on C++?


Thanks for any replys, these questions may make me look stupid, but I'm a noobie to C++.


P.S.
If you need the book's title and author it's On to C++ by Patrick Henry Winston

Yes, it does. Especially if it is one published in 1995.

Ideally, get a current book; for instance, C++ Primer 5th Edition (Lippman, Lajoie, and Moo)

Or at the very least, one published after 1998.

Okay, thanks for the reply! I'll either get that book or I'll use the online tutorial on this site.

Get a book. The online tutorial on this site is nowhere near adequate.

Slightly dated (does not cover things added in C++11), but Eckel's 'Thinking in C++' is available as a free ebook. http://mindview.net/Books/TICPP/ThinkingInCPP2e.html

A comprehensive online tutorial (which assumes familiarity with C):

In the second example you can put the line: using namespace std; above the main. That way you can just type cout<< instead of std::cout<<
