Create a Point class, implement Equality operator, Inequality operator, Comparison operator $($four$),$ Insertion operator $($make it as friend of Point class$),$ Arithmetic operators and Compound Assignment operator.

Show the Point class and explain to your teaching assistant step by step by using the four test cases.

Lastly, overload the subscript operator: $[],$ dereference $($indirection$)$ operator: $*,$ and apply $$Rule of three$$ to the Array class $($given below by my code$).$

Header File for step $3$:

#include

#include

#include

using namespace std;

class Array $\{$

public:

explicit Array$($int sizeValue$)$; $//$constructor$.$ Use explicit when there is one paramater.

Array$($const Array& origArray$)$; $//$copy constructor

~Array$()$;

private:

int$*$ data;

int size;

CPP file for step $3$:

#include "Array.h$"$

#include

using namespace std;

Array::Array$($int sizeValue$)$: size$($sizeValue$)$

$\{$

data $=$ new int$[$sizeValue$]$;

$\}$

Array::Array$($const Array& myArray$)$: size$($myArray$.$size$)//$This specific line of code still confuses me$.$ Specifically, const Array& myArray.

$\{$

data $=$ new int$[$myArray$.$size$]$;

for $($int i $=0$; i $<$ myArray.size; i$++)$

$\{$

data$[$i$]=$ myArray.data$[$i$]$;

$\}$

$\}$

Array::~Array$()$

$\{$

delete$[]$ data;

I do not know what a friend function is$.$ I also do not know what an insertion operator is$.$ I have never heard of these things. Could you explain what these are and what to do for the problem? Below is the rest of the UML.

Private:

int x

int y

Public:

$+$Point$($int x$,$ int y$)//$ constructor

$+$operator$==($other: Point$)$

$+$operator!$=($other: Point$)$

$+$operator$<($other: Point$)$

$+$operator$>($other: Point$)$

$+$operator$<=($other: Point$)$

$+$operator$>=($other: Point$)$

$+$operator$<<()($friend of Point class$)($No idea what this is$.$ Please explain what an insertion operator is$/$does as well as a friend function in addition to how to implement them.$)$

$+$operator$+($value: int$)$

$+$operator$+=($value: int$)$
