Trace Tables | Test For Loops with Trace Tables
Trace tables can help you to trace the value of variables as each line of code is executed. The values of the variables are displayed in a table and will help you identify any potential errors or recognise what the code is actually doing. This video is particularly for Grade 10 IT students that have learned about For Loops.
In this video we explain how to set up your trace table, then trace a simple Grade 10 IT level question and then do a more complex Grade 11 IT level question which uses nested loops and arrays.
The programming language used in the videos is Delphi but you can apply the same technique and tips when you are tracing any other programming language.
