Scope Resolution Operator in C++ Example Tutorial

Scope Resolution Operator in C++ Example Tutorial is today’s topic. Scope resolution operator is used to access functions, variables which are not present in that particular scope but are existing in the program. In other words, the scope resolution operator is used to define the  function outside a  class; We can also use it to set a global variable which has the same name as of a local variable in that particular scope.

#Scope Resolution Operator in C++

The :: (scope resolution) operator is used to get the hidden names due to the variable scopes so that you can still use them.

The scope resolution operator can be used as both as unary and binary.

You can use a unary scope operator if the  namespace scope or global scope name is hidden by the particular declaration of an equivalent name during a block or class.

For example, if you have the global variable of name my_var and the local variable of name data_var, to access global data_var, you’ll need to use a scope resolution operator.

Scope Resolution Operator in C++: Applications Explained with Examples

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.

Unformatted input/output operations In C++

In this article, we will discuss the unformatted Input/Output operations In C++. Using objects cin and cout for the input and the output of data of various types is possible because of overloading of operator >> and << to recognize all the basic C++ types. The operator >> is overloaded in the istream class and operator << is overloaded in the ostream class.

The general format for reading data from the keyboard:

cin >> var1 >> var2 >> …. >> var_n;

  • Here, var1var2, ……, varn are the variable names that are declared already.
  • The input data must be separated by white space characters and the data type of user input must be similar to the data types of the variables which are declared in the program.
  • The operator >> reads the data character by character and assigns it to the indicated location.
  • Reading of variables terminates when white space occurs or character type occurs that does not match the destination type.
