Question

what does a function return do in a program?

a. it removes the parameter from the program.

b. it does the same thing as a parameter.

c. it returns a value.

d. it displays an error message.

Explanation:

In programming, the return statement in a function is used to send back a value (which can be a result of computations, a specific data, etc.) to the part of the program that called the function. Option A is incorrect as return doesn't remove parameters. Option B is wrong because a parameter is an input to a function, while return is for outputting a value. Option D is incorrect as return isn't for displaying error messages (error handling is done via other mechanisms like exceptions in many languages). So the correct option is C.

Answer:

C. It returns a value.
