A fourth noobie question - namespace std?

**Travis Dane** · 01-21-2003

Ok, i'l explain.

A namespace is like a word before every function in it to avoid
that it has the same name as another function.

demonstartion, whe want 2 integers, and whe want both of
them to be called name,but thats not possible so whe use a
namespace.

Code:

#include <iostream>

using namespace std;


namespace tom
{
int age=11;
}

namespace pete
{
int age=14;
}


int main()
{

cout << tom::age; // Print the age int stored in the namespace tom

cout << pete::age; // Print the age int stored in the namespace pete


return 0;
}

Easy as that, of course this long from everything but this are just
the fundementals.

As for the 'using namespace std;' , that just means you dont have to put 'std::' before everything you want to use for that namespace.

Include all your headerfules with ".h"
and just don't add using namespace std

in that case you can use it without prefixing it with std
for example

Code:

#include <iostream.h>
#include <string.h>

int main()
{
     cout << "I have not used std anywhere and it still works" << endl;
     cout << "Its outdated ofcourse " << endl;
      return 0;
}

great to hear it worked. my previous post was so you are at least exposed to it. just remember, that iostream.h is nonstandard and newer compilers will give you warnings for it.

are you using a c++ compiler or a vc++ compiler?

You do realize this thread is 2½ years old, don't you?
