The significance of pointers in C is the flexibility it offers in the programming. Pointers enable us to achieve parameter passing by reference, deal concisely and effectively either arrays, represent complex data structures, and work with dynamically allocated memory. Although a lot of programming ca...
In the above program, the“memory_allocation”function allocated the memory toptr_1. Theptr_1acts like a double pointer and stored a string named“linuxhint”which is printed on the screen. Output Conclusion Thepointer to pointeris a useful concept in C programming language that allows you to...
Introduction to the C Programming Language for Embedded Applications Variables in C Arrays in C What Is a Pointer? A pointer is a variable. Like other variables, it has a data type and an identifier. However, pointers are used in a way that is fundamentally distinct from the way in which...
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 Programming Language A variable known as a pointer is one whose value is the address of another variable; in other words, the pointer itself contains the direct address of the memory location. Before a pointer can be used to hold the location of a variable, it must first be...
