Syllabus content 2.3 Programming Candidates should be able to: 2.3.1 Programming basics • write a program in a high-level language (The nature of the language should be procedural and will be chosen by the Centre from a given list*.) • implement and write a program from a given design presented as either a program flowchart or pseudocode • write program statements for: ○ ○ the declaration of variables and constants the assignment of values to variables and constants ○ expressions involving any of the arithmetic or logical operators (given pseudocode will use the following structures: DECLARE : // declaration ← or // assignment) *Python, Visual Basic (console mode), Pascal/Delphi (console mode) 2.3.2 Transferable skills • recognise the basic control structures in a high-level language other than the one chosen to be studied in depth • appreciate that program coding is a transferable skill Cambridge International AS and A Level Computer Science 9608.
