GCSE CS Creating Trace Tables

A trace table is a tool that is used to help understand and debug computer programs. It is a table that shows the values of variables and the flow of control in a program as it is executed. They are typically used when you are trying to understand how a program works, or when you are trying to find errors in a program. It can also be used to help you understand the logic of a program, and to identify any potential problems or inefficiencies.

To use a trace table, you first need to create a table with columns for the different variables in your program and a column for the flow of control. Next, you run your program and fill in the table as the program executes. You can also fill in the table by hand as you step through the program, line by line. As you can see, the trace table shows the values of the variables at each step of the program, and how they change as the program runs.
