Description

Function differs from a Procedure only that it necessarily returns a value and can be used in expressions.

Based on the above-mentioned, a function which does not contain a return is itself erroneous. Corrections required:

• implement return if the implemented method is a function
• rewrite function to procedure if return is not needed
