What is scope resolution in C++?

Can you explain what scope resolution is in C++?

Sure! Scope resolution in C++ is used to define the context in which a variable or function is defined.

Why do we need scope resolution? Can you give an example?

We need it to avoid naming conflicts. For example, if you have a global variable and a local variable with the same name, you can use scope resolution to specify which one you mean.

How do you use the scope resolution operator (::) in C++?

You use it by placing it before the name of the variable or function. For example, ::globalVar refers to a global variable.

Are there any other uses for the scope resolution operator?

Yes, it's also used to define functions outside of a class definition, like ClassName::functionName().
