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 ofFunctio...
pointers are used in a way that is fundamentally distinct from the way in which we use “normal” variables, and we have to include an asterisk to tell the compiler that a variable should be treated as a pointer. Here are two examples of pointer declaration: ...
In C programming language, the concept of pointers is the most powerful concept that makes C stand apart from other programming languages. In the part-I of this series we discussed the fundamental concepts around C pointers. In this article, we will try
Pointers in C has always been a complex concept to understand for newbies. In this article, we will explain the difference between constant pointer, pointer to constant and constant pointer to constant. This article is part of the ongoing series on C poi
