A)

Program Plan Intro

Address of (&) operator:

The main purpose of address operator “&” operator in pointers is to return the memory address of variables.

When the address of operator “&” is placed before the pointer variable, it will hold address of the pointer variable.

Example Program:

//include necessary header

#include <iostream>

#include <string>

using namespace std;

//main method

int main()

{

//variable declaration

int a;

//display the address of the variable a

cout << &a;

}

Representing array using pointer notation:

  • In general, array will have a continuous allocation of memory bytes, to represent the values present in the array it can be represented using its subscript value.
  • So, to represent the values using pointer notation with an indirection operator the name of the array plus the subscript representing the value needs to be specified.
  • When we represent only the array name, it will indicate the first element of the array.
  • To represent the next element we need to increment the values by one to find the proceeding elements of the array.
  • When “&” operator is used before an array it will return the address of the corresponding value.
