2.2 Programming and problem solving

• Branching - a programming control structure where code selects one or more pathways depending on the evaluation of a boolean expression.
• Iterations - a programming control structure that repeats lines of code for a set number of times or until a condition has been met
• Sequencing - a program control structure in which lines of code are run in the order that they are scripted
• Decomposition - the process of splitting a problem into smaller, solvable sub-problems that are easier to program
