Code Tracing Quiz

What is the purpose of tracing code?

• To create charts for code segments

• To execute loops

• To write code more efficiently

• To track variables and output for troubleshooting logic errors

What is the first step in tracing the execution of a loop?

• Create a chart with columns for variables and output

• Initialize the loop control variable
