Member Variables

Classes may define member variables that each instance of that class contains. Class instances may retrieve those variables.

Declaring a member variable is done with member variable declare. It takes in the variable's privacy (as public, protected, or private), name in camelCase, and type.

Member variables can then be accessed with member variable, which takes in the privacy of the member variable, the instance to retrieve the member from, and the name of the member variable.

Privacy is needed for accessing variables because some languages, such as Python, have different naming conventions per member variable privacy.

class start : Person
    member variable declare : private name string
    member variable declare : private age double

    constructor start : public Person name string age double
        operation : { member variable : private { this } name } equals name
        operation : { member variable : private { this } age } equals age
    constructor end
class end

In C#:

class Person
{
    private string name;
    private double age;

    Person(string name, double age)
    {
        this.name = name;
        this.age = age;
    }
}

In Python:

class Person:
    def __init__(self, name, age):
        self.__name = name
        self.__age = age
