The difference between the keywords public, static and void

The C# programming language has three important keywords that are essential for any programmer to understand. These keywords are public, static, and void. Each has its own distinct meaning and purpose, and an understanding of these concepts is necessary for a successful C# programming experience. 

Public: 

The public keyword is used to declare that a particular class, method, property, or field is accessible from outside the class. This means that it is available to any other object or class that has access to the object. When a class is declared public, it can be used by any other class, regardless of where that class is located. This makes public classes ideal for creating library classes that can be used by other classes. 

Static: 

The static keyword is used to declare that a particular property, method, or field is independent of any instance of the class. This means that the property, method, or field exists outside of any instance of the class and is not affected by any changes to the class. This is useful for creating methods and properties that are shared by all instances of a class. For example, a static field in a class can be used to store a value that is shared by all instances of the class. 

Void: 

The void keyword is used to declare that a particular method does not return any value. This means that the method does not return a value when it is called. This is useful for methods that perform some action but do not need to return any data. For example, a method that prints a message to the console does not need to return any data, and so it can be declared as void. 

In summary, the public, static, and void keywords are essential for C# programming. Public classes are accessible from outside the class, static fields and methods are shared by all instances of the class, and void methods do not return any data. Understanding these keywords and their meanings is essential to becoming a successful C# programmer.
