Answer / raghanna
A function pointer is a variable that stores the address of a function that can later be called through that function pointer. This is useful because functions encapsulate behavior. For instance, every time you need a particular behavior such as drawing a line, instead of writing out a bunch of code, all you need to do is call the function.

A function pointer is a type of pointer in C, C++ and other
C-like programming languages. When dereferenced, a function
pointer invokes a function, passing it zero or more
arguments just like a normal function. In programming
languages like C, function pointers can be used to simplify
code, such as replacing large switch statements.
