InC programming language, 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 ofFuncti...

Although we assign the address of printInt function, that takes a single int argument to the void (*func)(void) type function pointer in the following example. Once the function pointer named func is defined, it can be called with the usual function call notation func(arg) or with ...

Function Pointers in C - A pointer in C is a variable that stores the address of another variable. Similarly, a variable that stores the address of a function is called a function pointer or a pointer to a function. Function pointers can be useful when y

In this example, foo is a pointer to a function taking one argument, an integer, and that returns void. It's as if you're declaring a function called "*foo", which takes an int and returns void; now, if *foo is a function, then foo must be a pointer to a function. (Similarly...
