What is an Array?
Lets the user store lists of data in one variable
What is a fixed loop?
Repeats a loop a set amount of times
What is a conditional loop?
Repeats a loop until it is declared as true
Used for input validations
How do you implement a running total?
Total = 0 Total = total + 1
What are the 3 Pre-Defined Functions
Round
Random
Length
3 Types of Errors
Syntax Error
Executional Error
Logic Error
What is a Syntax Error?
Occurs when the rules, of programming language that is being used, is broken.
Eg; forgetting to close a loop or close a bracket.
What is a Executional Error?
Causes the program to crash even if there appears to be nothing wrong with it
What is a Logic Error?
When the program runs but does not do what its supposed to
Give an example of an operator
=, AND, OR, * etc
3 design methods
Pseudocode
Flowcharts
Structured diagram
What is normal data?
Data the program should accept
What is extreme data?
Data that is on the limits but is accepted
What is exceptional data?
Data that is beyond the limits and should be rejected by the program
3 Standard algorithms
Input validation
Running total
Traversing an array
6 stages of programming
Analysis Design Implementation Testing Documentation Evaluation
Evaluation stage
Is it fit for purpose Readability Meaningful variable names White space Robustness
What is an iterative process?
Previous stages in development are
often revisited
