The prototype for a function is shown below. what is the second parameter?
void glop( int *w, int (*second)( char x, char y ) );
a. a structure consisting of two characters.
b. a pointer to an integer which is accessed as two characters.
c. a pointer to a function which takes two integers and returns a character.
d. a pointer to a structure containing two characters.
e. a pointer to a function which takes two characters and returns an integer.

E. A pointer to a function which takes two characters and returns an integer.

Explanation:

Given function prototype:

void glop( int *w, int (*second)( char x, char y ) );

First parameter is a pointer to an integer.

Second parameter of the glop function: int (*second)( char x, char y );

Here second is a pointer to a function which takes two char data as inputs(char x and char y) and returns an integer datatype. So of the given options 'E' is the correct one.
