Which term refers to the chart that lists data values as a program executes?

• A. Variables
• B. Constants
• C. Data types
• D. Trace table

Answer: (D)

Tracking how values change as code runs is often done with a trace table. A trace table is a chart that lists the values of variables at each step of execution. As you step through the program, you record the current values for each variable in each row, so you can see how the algorithm progresses and where logic may go awry. This makes sense here because the question asks for a chart that shows data values while the program executes. Other terms describe static aspects of the program: variables are locations that hold data, constants are values that do not change, and data types describe what kind of data is stored. The trace table specifically captures the dynamic behavior—the changing values—during execution.
