i see
std::cout

a lot. is that becaue that dont name

using namespace std; at the top?

if it's a small program, declaring a global usage of the std namespace works without problems... but once you get into a complex project, with namespaces of your own, and others, and you've got a million different object scopes, it wont work out so nicely...

it's just good practice to use std::

so, just do it now, and later it'll make more sense to you as to why it's good to do it

but like I said, using namespace std; works you just need to know what it's doing ( :: )

hey, where did your dancing Bart go? I liked it!

add this line to the top of your code, and you could use cout simply.

PHP Code:


#include <iostream>

**d00b** · 07-30-2002

I think you mean

PHP Code:


#include <iostream.h>

<iostream.h> (old version of iostream and it's recornized by old compiler)

<iostream> (new version and it's unrecornized by old compiler)

yup, so if he used <iostream.h> he wouldn't have to worry about namespaces

Instead, he gets to worry about newer compilers not including <iostream.h>. Also, it is perhaps good to keep in mind that for the most part, software is updated for a purpose

Me too! look mine says N00B

**endo** · 07-31-2002

Ruski's is the coolest avatar I've ever seen, I'd like one similar but can't be bothered to search for one.

If std::cout is good practice what about putting using statements at the top instead?

using std::cout;
usin std::endl;
etc, etc

They're fine... what I'm getting at is that it's not good to just slap "using ....." at the top of code because you've been told to, you need to know that it's a shortcut from having to write out the scope of something over and over; that's all I'm saying

and about the <iostream.h> thing, I wasn't serious about actually using that, I was saying that if you wanted to avoid having to specify the std scope for iostream, that you could use that... but, don't do it
