What is the primary purpose of using 'static' in programming?

• To ensure variables are deleted after function execution

• To make variables accessible only within a function

• To enable variables to retain their value across function calls

• To allow variables to change dynamically

How does 'static' affect a method in a class?

• It makes the method accessible without creating an instance of the class

• It ensures the method is executed only once

• It allows the method to be overridden

• It restricts the method to be used only within the class

In which scenario is using 'static' most beneficial?

• When you need a variable to be deleted after use

• When you want a variable to be unique to each instance of a class

• When you want a variable to be accessible only within a loop

• When you need a variable to be shared across all instances of a class

What is a potential drawback of using 'static' excessively?

• It can lead to increased memory usage

• It can make code less flexible and harder to maintain

• It can make variables inaccessible from other classes

• It can cause variables to lose their values unexpectedly

Which of the following is a best practice when using 'static'?

• Always use 'static' for methods to simplify code

• Use 'static' only when necessary to avoid unintended side effects

• Avoid using 'static' in large projects

• Use 'static' for all variables to improve performance
