Which term refers to names used only inside a procedure?

• A. Parameters
• B. Local variables
• C. Global variables
• D. Library routines

Answer: (B)

The main idea here is how identifiers are scoped in programming. Names that exist only inside a procedure belong to its local scope. They are created when the procedure starts running and are gone when the procedure finishes, so they can’t be accessed from outside. This keeps data private to that procedure and prevents clashes with names in other parts of the program. While parameters are also local to the procedure and serve as its inputs, the phrase describes the names declared within the procedure body as local variables.
