S6:EP4 Understanding Algorithms and Flowcharts

This episode introduces algorithms, defining them as a series of steps to solve a problem, and highlights their presence in everyday tasks. It focuses on using flowcharts as a tool for planning and representing algorithms, detailing various flowchart symbols such as terminals, input/output, process, decision, and sub-program symbols, along with lines indicating flow direction. The material also explains arithmetic operators for calculations and the concept of variables as memory locations for storing values within an algorithm. Finally, it outlines three fundamental program structures—sequence, selection, and iteration—demonstrating how they control the flow of an algorithm using flowchart examples.
