1. Getters and Setters #

Created Wednesday 08 January 2020

What are setters and getters? #

They are public functions created by us, which set the variables and return/print them to the outside(of the class)

Why use getters(accessers) and setters(mutators)? #

• They are used for abstraction.
• Setters can check constraints imposed by us.

• Getters can return print data in a specified format.
• It adds a layer of authorization. We may need to provide the passwords.

• When making a real world project, we **should **set important(complex, or irrelevant to the user) members as private, in order to avoid any problems.
• The security here does not mean from outsiders. It is actually for achieving abstraction.
