Can any one tell me in c++ where we use namespace std and where we not use it ???

Question

use of namespace std

Answer 1

Samrat✌✌ ,if you don't use it, you will not get details from std namespace...
other way to work without namespace is use std::cout , std::endl as per requirement rather than entirely loading namespace std

Answer 2

Samrat✌✌ well you can define your own namespaces in c++, so if the need for that ever arises, you won't be only using std

Answer 3

it's usually not used when you'll potentially be working with multiple namespaces, because things can get muddled up

Answer 4

Samrat✌✌ all defined in namespace std... for example cout, endl
