What is Namespace?

[sunveer]

Namespace is basically a group of classes, objects or functions that are given one name.

So to use any predefined class or function in your program, you first have to include the appropriate namespace in your program to use that class or function.

Using namespace is according to the latest ANSI standards.

TC is an old compiler. Avoid using it.

Example of using namespace in C++

#include iostream.h (sorry if i use < >, i whole iostream is missing here)
using namespace std;
{
cout<<"Hello";
}

output : Hello
