The C++ programming language offers several operators to the programmers to help them manipulate complex data and compute accurate results. One of them is the scope resolution operator (: :).

Programmers often would like to access variables with the same name but with different scope. The scope resolution operator in C++ is the solution to this problem. The variable scope must be resolved according to where they are accessed. If the scope of the referenced variable is not resolved explicitly in C++, the compiler will simply access the innermost variable by default.

True to its name, the scope resolution operator can be used to access and manipulate variables with the same name but varying in scope. In this blog, we discuss how to use C++’s scope resolution operator for different programming purposes.
