hello peepz...
im another newbie in c++...
hope will learn much in time..knowledge is cool ))
btw
i got deitel's book for c++...anythin other that i may need u think??

[Valmont]

Welcome sir.

Experiance is the teacher mostly. So that's what you'll need I think.

[cracksevi]

so true...but will have no experience by knowing nottin about the proggie hehe
so lets learn and earn experience with the knowledge )

[cracksevi]

here i come with a basic question....
i noticed many ppl use this :


using namespace std;


this is the command for not using std:: each time correct?

[redhead]

Yes

[cracksevi]

for example :
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
using std::ios;

#include <iomanip>
using std::setprecision;
using std::setiosflags;






these can be shortened by anyway?

[Valmont]

Yes. Although it is not advisable to do so. This is what I earlier wrote:

Ok.

C++ has a standard as defined by a certain comittee called ISO. ISO C++ is the international operating independent C++ standard. ANSI, also important, is the American C++ standard.
The fact that I am using <iostream> etcetera WITHOUT the .h extension means that I am going to to program in standard C++. But using standard methods and functions and algorithms and containers means that I need to enter this all the time:
std::cout; std::cin ; std::getline; and so forth.
So what I do is define it in once like this:

using std::cout;
using std::cin;
using std::endl;
using std::string;

I could do it even simpler: using namepsace std; .
But now I am forcing everybody to use standard C++ for the headers that I included in the file. That is not very professional. That's why I did it this way. A sort of in-between way.

[cracksevi]

so is more proper to do in this way....
i just wondered if it could be more simplified..but better to do as u say...u the master..not me..
it will take some while till i learn the basics i think
but one day i will succeed
thanx for the infos bro
