#include "stdio.h"
aaa() {
	printf("hi");
}
 
bbb(){
	printf("hello");
}
 
ccc(){
	printf("bye");
}
 
main()
{
	int (*ptr[3])();
	ptr[0]=aaa;
	ptr[1]=bbb;
	ptr[2]=ccc;
	ptr[2]();
}

Answer:
bye

Explanation:
ptr is array of pointers to functions of return type int.ptr[0] is assigned to address of the function aaa. Similarly ptr[1] and ptr[2] for bbb and ccc respectively. ptr[2]() is in effect of writing ccc(), since ptr[2] points to ccc.
