C++ question - Classes - question 2 is part of question 1

-----------------------------------------------------

Exercise 1: Implement the Array class that is defined below and test it in the main program. The main program must test all the functions that are defined in the class.

#ifndef array_h

#define array_h

class Array { // Class declaration

public:

Array (int =5); //Initialize the array with 0 values

Array (const Array & ); // copy constructor

~Array(); //destructor

bool setValue (int index, int value); // assign a value to an

//array element

bool getValue (int index, int &value); // get an array element

Array & increment(); /* cascade function to increment each array element by 1 */

int getSize ( ); // return the size of the array.

void print ( ) const; // print each element of the array

Array& Add(const Array ar);/*casade function to add all elements of arr to all elements of the this array (element by element) and return a reference to the resulting array */

bool Equal(const Array *ar)const;// return true if all elements in both arrays are equal, false otherwise.

Array& removeAt(int index);//cascade function to remove element at the index.( if index is within the valide range, you should allocate new memory with 1 element less, copy all elements but the element at index to new memory, delete the old one)

Array& insertAt(int index, int value);// insert value at index location, if index is greater than the size, then insert the element at the end of the array, if index is < 0 then insert the element at the beginig of the array, otherwise, insert in the exact index ( you should allocate new memory, copy element etc)

private:

int size; // size of created array

int* arr;

};

#endif

Exercise 2: sumArray ( ) is a function that sums all the elements of a given array object. Implement sumArray ( ) using the three techniques that we have learned in the lecture, namely:

As a non-member function of the class Array

int sumArray ( const Array &);

As a friend function of the class Array

friend int sumArray ( const Array &);

As a public member function of the class Array

int Array::sumArray ();
