You are required to write a C$++$ program that processes

an Electric$\_$Bill class through various operations.

Please address the following sub$-$questions:

$1.$ Create an Electric$\_$BIll class with the following

specifications:

It should have private attributes for the yearly bill, which

is an int array of $6$ years$$ data, and another similar array

for reversed bill data.

In main function, define two int arrays:

$\{230,270,190,560,350,260\}$ and

$\{150,230,770,590,100,520\}.(4$ points$)$

$2.$ Provide a constructor and initialise two objects

$($named Comp$1$ and Comp$2)$ using the two arrays above.

Implement a member function of

class Electric$\_$BIll called show to display the raw

yearly bill data, call this function in the main function to

show the bill data of Comp$1$ or Comp$2.(6$ points$)$

$3.$ Implement two member functions

of Electric$\_$BIll class:

$(1)$ Write a reverse function to reverse the bill data in

Comp$1$ and call this function from main function. $(6$

points$)$

$(2)$ Write two member functions named Max and Min

and return the year index of the maximum and minimum

of Comp$2$ and call it from the main function $($e$.$g$.$ for

Comp$2$ should return $3.(6$ points$)$

$4.$ Overload the operator $-$

in Electric$\_$Bill class to calculate the subtraction

of Comp$1$ and Comp$2,$ and use Comp$1-$Comp$2$ to return

delta $($this should be another Electric$\_$Bill object$)$

and display the bill data of delta in main function. $(8$

points$)$
