What is the term describing the method of displaying the flow of a program's executions?

• A. Execution path
• B. Flow diagram
• C. Trace route
• D. Call graph

Answer: (C)

The concept being tested is how we represent what actually happens as a program runs. The standard term for this is an execution trace, or simply a trace. It records the real sequence of events—each executed statement, branch taken, and function call—in the order they occur, providing a concrete view of the program’s flow during a specific run. This is different from a flow diagram, which is a static diagram of possible paths; a call graph, which shows which functions call which others; and a trace route, which is a networking term for mapping packet paths. So the best-fitting idea for displaying a program’s execution flow is an execution trace.
