Software Design and Development (Implementation: Algorithm Specification)

Question 1

What are the three main algorithms in Software Design and Development?

Answer 1

Input Validation
Running Total Within Loop
Traversing a 1D Array

Question 2

What does a pre-test conditional loop do?

Answer 2

A pre-test conditional loop checks the conditions before the code within in loops is translated

Question 3

What does a post-test conditional loop do?

Answer 3

A post-test conditional loop will execute all code within the loop at least once before checking the condition

Question 4

What is the basic pseudocode for collecting a running total in an array?

Answer 4

SET totalScore TO totalScore + score[n]

Question 5

What is the purpose of an input validation algorithm?

Answer 5

To make sure that data received from the user is valid for the task at hand

Question 6

What is an example of a pre-test conditional loop often used as part of input validation algorithms?

Answer 6

WHILE…END WHILE

Question 7

What is an example of a post-test conditional loop, sometimes used as part of input validation algorithms?

Answer 7

FOR…FROM…TO…DO…END FOR

Question 8

What is a description of ‘traversing an array’?

Answer 8

Access each element in an array so that data can be checked, altered or used
