Scope resolution operator??

Question

What does a scope resolution operator(::) do? It’s one of the only things in c++ i don’t exactly know.

Answer 1

Scope resolution operator is used when we want to use an object or namespace
For example: If we don't do (using namespace std;), we would need to add (std::) in every objects of standard libraries because std is the namespace of standard.
