Trace code involves...

• A. Writing down values of variables and how they change each loop iteration.
• B. Optimizing code for speed
• C. Profiling performance
• D. Encrypting data

Answer: (A)

Tracing code is about following a program’s execution step by step and recording the values of variables as the program runs, especially how they change inside loop iterations. This helps you see exactly what happens at each step, verify that the loop counter and conditions behave correctly, and catch logic errors that aren’t obvious from reading the code alone. The other activities describe different goals: making the program run faster, measuring how well the program performs, or securing information through encryption. Tracing is the practice of visualizing the program’s state over time to understand its behavior.
