Handling data in algorithms
i) Define the terms variable and constant as used in an imperative language
ii) Use variables and constants
iii) Describe the data types integer, real, boolean, character and string
iv) Select an justify appropriate data types for a given program
v) Perform common operations on numeric and Boolean data
vi) Use one dimensional arrays
This section is all about handling data within an algorithm or program. Data come in various forms and so they need to be handled differently. This mini-web covers the data types you need to learn.
