What are the differences between the following:
- Private Sub
- Private Function
- Private Class
When should each one be used?
回答1:
Private is a modifier than gives the scope of the class, sub, or function.
A sub and a function are both subroutines, or sections of code that can be called in the program. The difference between them is that a function has a return value and a sub does not.
A class is a group of codes that can include subs, functions, and other stuff.
回答2:
Sub is like a function but it doesnt returns any values it just executes a proccess
回答3:
Class is a Class, Sub and Function are methods, private is an access modifier
