Types of testing framework for development
Acceptance testing This is the final testing phase based on user needs, where the functional requirements gathered during the “investigate” stage are verified to ensure […]
Common algorithms
NOTE: You do not have to “memorise” the code examples below, but you must be able to understand what each line of code does! You […]
Good programming practice
Validate input before processing All inputs to a program should be validated for correctness before they are used in further processing to prevent runtime or […]
Characteristics of array and dictionary data structures
An array is a collection of elements, each identified by at least one array index or key. An array is a data structure that stores […]
Different types of operators
Arithmetic operators +, -, *, /, % Arithmetic operators perform common mathematical operations on values. ‘%’ is for modulo (remainder after division). Example: 5 % […]
