namespace: is it good?

[FrancescoItaly]

Hi all, sorry for the topic's title, but I have not found anything better.

... So, is it better write:

#include <iostream>
using namespace std;

or this?

#include <iostream>
using std::cout;
using std::cin;
......

Bye all!

[Galik]

This is considered better:

#include <iostream>
using std::cout;
using std::cin;

But I personally prefer:

#include <iostream>

// ...

int main()
{
    std::cout << "to just type std:: before standard symbols" << '\n';
}

@Galik thank you very much

Whichever you choose, please do not ever put using namespace std in a header file
