Function Pointers in C and C++By Alex Allain 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 ...
Pointers may also be used to point to functions. Provides a more flexible way to call a function, by providing a choice of which function to call. Makes it possible to pass functions to other functions. Not extremely common, but very useful in the right situations. Declaration A function p...
A pointer isused to store the address of variables. So, when we define a pointer to pointer, the first pointer is used to store the address of the second pointer. Thus it is known as double pointers. Application of Function Pointers in C 15 related questions found What is the correct wa...

In this blog, you will learn about functions in C programming, including their definition, types, and how to use them to make your code more modular and efficient.
Function pointers are for storing addresses of functions in order to execute those functions at a later time. Function pointers are similar to their counterparts in the C programming language. Deleg…
Function Pointers In C++, pointers are variables that hold the memory address of a variable. Similarly, a function pointer is a pointer that holds the address of a function. A function pointer can be declared with the following code: int (*point_func)(int, int); In the above code, poi...
, we can have a concept of Pointer to a function known asfunction pointer in C. In this tutorial, we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you should have the basic knowledge ofFunctionsandPointers in C....
state machine implementation in C With the help of array and function pointers, we can implement a state machine in C. The function pointer store the address of the function which will be invoked at defined state and events. A finite state machine is one of the popular design patterns, it...
