#INTRODUCTION TO #POINTERS & POINTER #ARITHMETIC

#Pointers in #C are easy and fun to learn. Some C #programming tasks are performed more easily with pointers, and other tasks, such as #dynamic #memory #allocation, cannot be performed without using pointers. So it becomes necessary to learn #pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. As you know, every variable is a #memory #location and every #memory location has its address defined which can be accessed using ampersand (&) #operator, which denotes an #address in memory. A pointer is a #variable whose value is the #address of another variable, i.e., direct address of the memory location. Like any #variable or constant, you must declare a pointer before using it to store any variable address.
