Trace Tables | Test your code 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.

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.

Hi Mr Long.👋
I am a matric student at a school in South Africa. I have been using your videos for studying purposes and they have helped improve my understanding and my marks, in both CAT and IT, exponentially! I wrote my CAT practical pre prelim the other day. I am the unofficial tutor for my class on these subjects. whilst frantically answering all my class' questions I sent a link to your videos and told them to watch them. We all had a much better understanding of the subject going into the exam and we are all in agreement that your videos are a literal life saver!
when I sent the video the one girl said "Where has this been all my life?! I needed this years ago!"
I just wanted to say a HUGE thank you from my me and my class.
Thank you!😁😜

Day Before Exam and I'm feeling confident with Trace Tables because of this video. I literally was doing a Past Paper and wanted to see how it was laid out in the memo. It was all wrong so I had to turn to the absolute G Mr. Long to seek assistance and Thank Heavens you released this video. Honestly a true life saver 🤌😁
