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 ext
As a conclusion, we have to cast a function pointer back to the original type in order to call a function, if we had casted a function pointer to a different function pointer type earlier. Here, read more on Function Pointers in C. ...
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...
If you really want to use function pointers in C++, you can still use the same C-style syntax shown above or the type aliases below. As a function pointer type alias: using typeName = returnType (*)(parameterTypes); (example code) As a function type alias: using typeName = returnType...

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...
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…
, 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...
