when a pointer points to the function and its return type is also a pointer then it is pointer to function . This concept is very useful in datastruct .

that stores the address of a function that can later be called through that function pointer. This is useful because functions encapsulate behavior....

function pointer point the directly source code instead of data. it can able to access the memory address directly so, no need to search in operating system lookup table.

Function pointers can be useful when you want to create callback mechanism, and need to pass address of an function to another function.
