Member Functions

Classes may declare member functions that each instance of the class may call.

Declaring a member function is done with member function declare start. It takes in the function's privacy (as public,protected, orprivate), name in PascalCase, return type, and any number of (name, type) pairs of parameters.

class start : Announcer
    member variable declare : private Greeting string

    member function declare start : public Greet void name string
        print : { concatenate : { member variable : private { this } Greeting } (", ") name "!" }
    member function declare end

    constructor start : public Announcer greeting string
        operation : { member variable : private { this } Greeting } equals greeting
    constructor end
class end

In C#:

using System;

class Announcer
{
    private string greeting;

    public void Greet(string name)
    {
        Console.WriteLine(this.greeting + ", " + name + "!");
    }

    Announcer(string greeting)
    {
        this.greeting = greeting;
    }
}

In Python:

class Announcer:
    def greet(self, name):
        print(self.__greeting + ", + " + name + "!")

    def __init__(self, string):
        self.__greeting = greeting

Calling

Call member functions with the member function command. It takes in the same function privacy, , caller's name, and any number of parameters.

• In C#: announcer.Greet("Sample");
• In Python: announcer.greet("sample")
