A procedure returns a value; a function does not

They are identical in all languages

A function returns a value; a procedure does not

A function cannot take parameters

They are quicker and more convenient for the programmer to type out in the code

They use up considerably more memory than global variables do while running

They are visible everywhere throughout the whole of the program at all times

They cannot be changed accidentally by other subroutines, avoiding side effects

A base case and a general case

A loop and a counter

A global variable and a parameter

Two return statements

A class is an instance of an object

A class is a template and an object is an instance of it

An object is a template and a class is an instance of it

They are the same thing

It lets a subclass derive its attributes and methods from an existing superclass

It makes the same method call behave differently for objects of different classes

It bundles data with its methods and hides the data behind public methods

It removes the need to define any classes at all within the program being written

Encapsulation

Inheritance

Instantiation

Polymorphism

It tests its condition before the body, so it can run zero times

It always runs its body at least once before the condition is ever tested

It is a form of definite iteration controlled by a fixed counter variable

It cannot be nested inside another loop or any other control structure

They are exactly the same thing and the two terms can be used interchangeably

A parameter is in the definition; an argument is the value supplied in the call

A parameter is the value passed in the call; an argument is named in the definition

An argument can only ever be a constant value and never a variable or expression
