What is the purpose of the `static` keyword in C#?It declares members that belong to the type itself rather than to any specific object of the type.It makes a method or variable immutable, so its value cannot be changed after it`s set.It ensures that only one instance of a class is created in the application.It marks a class as inheritable, allowing other classes to derive from it.

What is the purpose of the static keyword in C#?It declares members that belong to the type itself rather than to any specific object of the type.It makes a method or variable immutable, so its value cannot be changed after it`s set.It ensures that only one instance of a class is created in the application.It marks a class as inheritable, allowing other classes to derive from it.
Solution
The static keyword in C# has a specific purpose. It is used to declare members that belong to the type itself rather than to any specific object of the type. This means that the static member is not tied to any particular object instance of the class. Instead, it is tied to the class itself.
For example, if you have a class Car and a static member TotalCars, each time a new object of the class Car is created, TotalCars would not be allocated memory each time. Instead, it would be shared among all instances of the class.
The static keyword does not make a method or variable immutable. Immutability, meaning the value cannot be changed after it's set, is not a feature provided by the static keyword.
The static keyword also does not ensure that only one instance of a class is created in the application. This concept is related to the Singleton design pattern, which restricts a class to a single instance.
Lastly, the static keyword does not mark a class as inheritable. In C#, all classes are inheritable by default unless marked with the sealed keyword. The static keyword has no impact on a class's inheritability.
