What does the Navigator do?

• A. Reads the code to the driver and checks for errors
• B. Sends code to the compiler
• C. Executes the code directly
• D. Displays error messages only

Answer: (A)

The Navigator is about preflight validation. Its job is to inspect the source code, pass it along to the driver, and check for errors so problems can be caught early before anything is compiled or run. This helps catch syntax mistakes or obvious issues right away, making the subsequent steps smoother.

It isn’t the part that sends code to the compiler, and it doesn’t actually execute the code, and it isn’t limited to just showing error messages—the primary function is reading and validating the code to ensure the driver receives usable, error-free input.
