Coding from algorithms

This investigation looks at:
• what a 3GL computer program is; compiled and interpreted programs
• the basic constructs needed to make a program
• pseudocode, flowcharts, Nassi Shneiderman Diagrams, and structured development charts
• the role of sequence in programming
• using variables to store values; types of variables; declaring variables; naming conventions
• constants and comments
• selection: conditions and logical operators
• nested selection and case statements
• iteration: definite and indefinite, pre-tested and post tested
• subroutines: procedures and functions
• passing parameters by reference or value
• scope: local, module/unit, and global
• recursion.
This unit contains 8 classroom-tested activities to reinforce concepts, including the development of programs from algorithms.
