What are Trace Tables?

The purpose of the table is that we can run through an algorithm and simulate what a computer would do if the program were executed. We complete the table to show how the values within the variables change, what the conditions would evaluate to, and what outputs would be generated.

There are two main reasons that trace tables are used.

• The first is to determine what an algorithm does by running through it to see what happens as the algorithm runs.
• The second is to test the logic of an algorithm in case there are errors that are not easily spotted.
