Programs are designed and implemented using common building blocks, known as programming constructs. These constructs are sequence, selection and iteration and they form the basis for all...

Aug 27, 2018 · There are THREE basic programming constructs. They are: Sequence logic is used for performing instructions one after another in sequence. SELECTION. Selection logic, also known as decision logic, is used for making decisions. Selection logic is depicted as either an IF…THEN…ELSE or IF…..THEN structure. Selection is the decision-making construct.

This section explores programming fundamentals for computer science, topics covered include: variables and constants, the three basic programming constructs, count-controlled iteration, condition-controlled iteration, nesting, operators and applying computer aided mathematics.

Mar 31, 2018 · A sequence construct tells the CPU (processor) which statement is to be executed next. By default, in popular languages, this is the statement following the current statement or first statement in the program. In other words, this is the very basic construct of writing a program.

Mar 29, 2024 · Learn about Programming Constructs for your A Level Computer Science exam. This revision note includes sequences, selections, and iterations in programming.

Feb 27, 2025 · This video explains the three basic programming constructs of sequence, selection and iteration. It is assumed that students already have some programming experience with these constructs, and the purpose of this video is to marry the theory of programming to their practical experience in preparation for exams. Securing the key terminology.

Using a projector, show the video (http://www.cambridgegcsecomputing.org/weblink21) and then click on the Explanation button (once) to display some statements about the video and iteration. Stress that iteration leads to eficiency – the same code can be used many times – no need to rewrite it. Show students the link to the specification.

Jul 29, 2024 · What is a Programming Construct? A programming construct determines the order in which lines of code are executed. They control logic and behaviour of code. There are three core programming constructs: Sequence. Selection. Iteration
