just go thru the two examples written below, to clarify this doubt

ex of pointer to function:

int (*function name)(Argument1,Argument2..)

The above decleration explains that its an pointer to a function whose return type is an intiger.

ex of function to pointer :

int *function name(Argument1,Argument2..)

The above declaration expalains that a function teturns a pointer to an intiger quantity.

The question as written is meaningless.

The term 'function to a pointer' doesn't exist in standard C.

In the answer the 'function to a pointer' example is a function prototype that returns a pointer to an integer, therefore the question should be rephrased 'What is the difference between a pointer to a function and a function that returns a pointer?'

And if you don't know the answer to that, we should end the interview right here...
