C Pointer to a function
In this section, you will learn how to use 'Pointer' function in C.
C provides a special feature of pointer to a function. As you know that every function defined in C language have a base address attached to it. This base address acts as an entering point into that function. This address can be stored in a pointer known as function pointer. The pointer to a function is the declaration of pointer that holds the base address of the function. The declaration of a pointer to a function is:
You can see in the given example, we have create a function mul to find the product of three numbers. Then we have declared the function pointer for storing the base address of function mul in the following way:
int (*function_pointer) (int,int,int);
Here is the code:
