The get method returns the value of the variable name . The set method assigns a value to the name variable. The value keyword represents the value we assign to the property. If you don’t fully understand it, take a look at the example below.
When we use get and set in C#?
In properties, a get accessor is used to return a property value and a set accessor is used to assign a new value. The value keyword in set accessor is used to define a value that is going to be assigned by the set accessor. In c#, the properties are categorized as read-write, read-only, or write-only.
Why we use get and set in C++?
The meaning of Encapsulation, is to make sure that “sensitive” data is hidden from users. To achieve this, you must declare class variables/attributes as private (cannot be accessed from outside the class).

What is getter and setter in C#?
Getters and setters are methods used to declare or obtain the values of variables, usually private ones. They are important because it allows for a central location that is able to handle data prior to declaring it or returning it to the developer.
Why we use lazy in Swift?
Lazy variables allow you to delay the initialisation of stored properties. This can be useful to only perform expensive work when it’s actually needed. The different between lazy- and computed properties is important in cases you need to have calculations based on the current state of values.
What is computed property?
A computed property is a property that calculates and returns a value, rather than just store it.
