Review-Paper 1

The games club is looking at two programming paradigms: imperative and object-oriented programming paradigms. Describe what is meant by the imperative programming paradigm. Choose three

• A sequence of steps that change the state of the program

• Creates classes

• Subclasses can inherit from superclasses (child and parent)

• Groups code into self-contained blocks // split the program into modules

• The steps are in the order they should be carried out

The games club is looking at two programming paradigms: imperative and object-oriented programming paradigms. Describe what is meant by the Object-Oriented programming paradigm. Choose two

• A sequence of steps that change the state of the program

• Creates classes

• Subclasses can inherit from superclasses (child and parent)

• Groups code into self-contained blocks // split the program into modules

• The steps are in the order they should be carried out

Some algorithms can be written using recursion. State three features of recursion.

• It is defined in terms of itself // it calls itself

• It can return data to its previous call

• When the stopping condition/base case is met

• …the last set of values are taken off the stack (in reverse order)

• It is a self-contained subroutine

Click which are the purpose of a user-defined data type. Choose two

• To create a new data type (from existing data types)

• To create a new data type (from new data types)

• To allow data types not available in a programming language to be constructed

• To stop the flexibility of the programming language

Click the appropriate description about the given Operating System below:

MULTI-TASKING

• Locating non-contiguous blocks of data and relocating them

• Managing the execution of many programs that appear to run at the same time

• Managing the processes running on the CPU

• Reading/writing same-size blocks of data from/to secondary storage when required
