What happens if the return statement has no related expression?

b) It will throw a exception

c) It will return the 0 as the value

d) It will throw a error

Answer 1

Answer: A

Reason: Suppose a function that does not have a return statement in its definition returns a default value. Although the return statement is mentioned in the definition, but not associated with the expression, then it will return the value known as "undefined."
