CPT Program Trace Builder
A simple manual tool for tracing program execution step-by-step for AP CSP CPT practice.
CPT Program Tracing Overview
In AP CSP, “tracing a program” means explaining how a program runs step-by-step.
You should describe:
- Input or starting state
- How values change during execution
- How loops repeat actions
- How conditions affect decisions
- Final output
Key idea: You are tracking execution over time, not just describing code.
