Flowcharts & Trace Tables


Flowcharts & Trace TablesOnline version Two students compare flowcharts and trace tables. by Pooja Arora Alex Today we're learning about flowcharts and trace tables for IBDP CS. Maya Great! Flowcharts visualize algorithms, and trace tables track values. Alex Flowcharts use shapes: ovals start/end, rectangles for processes, diamonds for decisions. Maya Trace tables list variables and their values at each step. Alex Let's try a simple example: sum numbers from 1 to n. Maya In the flowchart, we'd have input n, initialize sum and i, and loop until i > n. Alex For the trace table, we record i and sum at each iteration. Maya This helps us verify the algorithm behaves correctly. Alex Could you draft the corresponding pseudocode from the flowchart? Maya Yes, then we compare it with the trace table to validate outputs.
