Explain keywords with example.
Keywords are those words that are reserved to be used for an exact task. These words cannot be used as identifiers. You cannot use a keyword to explain the name of a variable or method. Keywords are used in programs to use the features of object-oriented programming.
For instance, the abstract keyword is used to execute abstraction and the inherits keyword is used to execute inheritance by deriving subclasses in C# and Visual Basic, respectively.
The new keyword is universally used in C# and Visual Basic to implement encapsulation by creating objects.
