➢ Arrays and pointers are intimately related in C and often may be used interchangeably. ➢ An array name can be thought of as a constant pointer.
Unlike other variables that hold values of a certain type pointer holds the address of a variable. For example

In C we use pointer as a reference. (vi) Storage of strings through pointers saves memory space. (vii) Pointers may be used to pass on arrays
After numerous requests I've finally come out with this PDF version which is identical In C when we define a pointer variable we do so by preceding its.
Pointers in C are easy and fun to learn. Some C programming tasks are performed more easily with pointers and other tasks

bounds memory access in C programs and to confirm it on concrete test data. However this is not directly possible for input arrays/pointers in C functions.

Pointers and Memory By Nick ParlanteCopyright ©1998-2000 Nick Parlante Abstract This document explains how pointers and memory work and how to use them—from the basic concepts through all the major programming techniques For each topic there is a combination of discussion sample C code and drawings
Pointers may be assigned and compared for equality using the usual operators Pointers may also be manipulated by incrementing and decrementing although doing so is only safe under precisely-defined circumstances By convention pointers without targets should be set to 0 (or NULL)
2 2 1 Declaring Pointers To declare a pointer variable named ptr that points to an integer variable named x: int *ptr = &x; int *ptr declares the pointer to an integer value which we are initializing to the address of x We can have pointers to values of any type The general scheme for declaring pointers is:
A pointer is a variable that represents the location (rather than the value) of a data item They have a number of useful applications Enables us to access a variable that is defined outside the function Can be used to pass information back and forth between a function and its reference point More efficient in handling data tables
pointer is an address in the memory One of the unique advantages of using C is that it provides direct access to a memory location through its address A variable declared as int x has the address given by &x & is a unary operator that allows the programmer to access the address of a single variable declared
