1.4 principles of programming

Each line of high level language equates to ______ ______ of machine code

(a)  

A situation that would require the use of a low level language is:

• Device drivers

• using long and meaningful identifiers

• writing a module that can be reused.

• using a mark-up language

what programming paradigm uses classes?

• procedural

• visual

• object-oriented

• mark-up

A class is a programming (a)   for creating objects

Backus-Naur form is used to

• describe the operating system in a computer

• decode assembly instructions

• describe unambiguously the syntax of a programming language

• describe the instructions for a particular chip set

Which of these pictures shows recursion in BNF form?

• 
• 
• 
• 

This symbol ::= in Backus-Naur form means:

• OR

• AND

• is defined by

• is equal to

An advantage of using a procedural language to write a program based on an algorithm is:

• is more modular than an object-oriented language

• allows the programmer to wait for an event before activating a procedure.

• can be used to create a web page.

• Allows the programmer to define precisely each step when performing a task

Final output values in Backus-Naur are called

(a)  

OR in Backus-Naur is written as

• |

• ¬

• ::=

• ::
