How Are Pointers Related to ArraysOk, so what's the relationship between pointers and arrays? Well, in C, the name of an array, is actually a pointer to the first element of the array.Confused? Let's try to understand this better, and use our "memory address example" above again. ...
Example 1: C++ Pointers and Arrays // C++ Program to display address of each element of an array#include<iostream>usingnamespacestd;intmain(){floatarr[3];// declare pointer variablefloat*ptr;cout<<"Displaying address using arrays: "<<endl;// use for loop to print addresses of all array ...
The notion of pointers has been around computing from very early times, but traditionally their availability in Fortran has been rare so, presumably, many readers are not familiar with them. Conceptually, a pointer is a variable that does not itself contain data of interest but rather holds ...

Well, the former one is a pointer to an array of 10 integers, and the later one is the name of an array of 10 pointers to type int. Refer tohttp://home.netcom.com/~tjensen/ptr/ch8x.htmfor learning the basic pointer concepts of C....
Example: Arrays and Pointers Following example print i) array elements using the array notation and ii) by dereferencing the array pointers: Code: #include<stdio.h>intnums[]={0,5,87,32,4,5};int*ptr;intmain(void){inti;ptr=&nums[0];/* pointer to the first element of the array */pr...

You can define arrays to hold a number of pointers. 5 Pointer to Pointer C++ allows you to have pointer on a pointer and so on. 6 Passing Pointers to Functions Passing an argument by reference or by address both enable the passed argument to be changed in the calling function by the...
