Scope resolution operator in C++ is one of the essential operators which is used to identify and access the entities that are defined outside the current scope of a program. In simple terms, it allows a programmer to access global or namespace-level entities within a function or a class. This article discusses scope resolution operation in C++, its syntax, its purpose, and applications of scope resolution operator in C++.<\/p>\n

What is Scope Resolution Operator in C++?<\/h2>\n

The scope resolution operator in C++ is represented by two colons (::) and is used to access entities that are defined outside the current scope of a program. This operator is also known as the global scope operator.<\/p>\n

Let’s take an example to understand more clearly, suppose we have two integer variables defined as valuation, one is declared globally and one locally. Both integer variables have different scopes and to access the global variable valuation inside the local scope, the resolution operator "::" is used as follows:<\/p>\n
