Answer the following questions:Clearly and precisely explain why and when do you need a copy constructor? What is the relationship between pointers and arrays? Consider the integer array “int myArray[] = { 2, 4,6};”. Show the syntax for accessing the last element in “myArray” using array indexing notation first then using pointer notation.

1. Copy Constructor A copy constructor is a type of constructor that is responsible for initializing an object using the another object of the same class. A constructor which is useful for creating an object by initializing the created object with the help of an another object of the same class, that has been previously created is called a copy constructor. Need of Copy constructor The copy constructor is responsible for initializing the members of a recently created object by copying the members of an object that has already been created. Copy constructor takes a reference to a particular object of the same class as a parameter. Rectangle(Rectangle &obj) { length = obj.length; breadth = obj.breadth; }Rectangle r1(10, 8);Rectangle r2 = r1;The above defined constructor is a copy constructor that takes an object of the same class and intitialise the members by copying the members of the object r1 2. Pointers and Array Array is used to store elements of same data types , whereas Pointers are address variables which are responsible for storing the address of another variable. Array variable also contains an address which can be pointed out by a particular pointer and array or array elements can be accessed by using that pointer. int myArray[] = {2, 4,6}; For accessing the array element at an index i, syntax for the same would be arr_name[i]. So the last element is present at an index 2, thus syntax would be myArray[2] For accessing the array element at an index i using pointers, syntax for the same would be First declaring the pointer and initializing the pointer with the array address int *ptr = &arr_name[i]. Then dereferncing the pointer *ptr So the last element is present at an index 2, thus syntax would be int *ptr = &arr_name[2] cout << *ptr << endl; (In c++)
