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

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

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