Create a header file for a class called Statistician

Create a default constructor Statistician$()$

Create the next function

void next$($double num$)$

Include the $+$ operator as a binary operator so that it combines two Statistician objects.

Statistician operator $+($const Statistician& s$1,$ const Statistician& s$2)$;

Create getters for the variables:

average

total

num$\_$items

maximum

minimum

Create the following double private variables:

average: represents the average of all of the numbers passed in through the next$()$ function

total: represents the total of all the numbers passed in through the next$()$ function

maximum: represents the largest of all of the numbers passed in through the next$()$ function

minimum: represents the smallest of all of the numbers passed in through the next$()$ function

Create an int private variable called num$\_$items represents the total number of nums passed in through the next function. This is a counter.

Create the implementation file $(.$cpp file$)$ for the Statistician

The default constructor Statistician$()$ should assign zeros to total, average and num$\_$items.

Code for the plus operator should:

add the totals together, add the num$\_$items, recompute the average, compare the two maximums and assign the larger of the two to the resulting Statistician and similar process for minimum.

Code for the next function

Should add $1$ to the num$\_$items

initialize maximum and minimum to the num passed in if num$\_$items is equal to $1.$ Otherwise, if num is bigger than maximum then maximum should be assigned num. If num is smaller than minimum, then minimum should be assigned the value of num.

Add num to the total

Update the average. Note average $=$ total $/$ num$\_$items

Create a driver file $(.$cpp file with main$()),$ that creates a default Statistician object, s$1.$

Call the next$()$ function on the object with the following values: $2,8\mathrm{.}5,3,0,10$

Sample usage:

obj.next$(2)$;

obj.next$(8\mathrm{.}5)$;

Repeat for each of numbers in the list. This function feeds the numbers to your Statistician object. Each call to the function updates all of the variables in the object.

Use the getters to display all of the variables in the object $($there are $5$ variables$),$ in the following format:

:$=$

Example: Information for num$\_$items would print as$...$

num$\_$items :$=5$

How do I know it is correct?

Your output should look like:

Console showing $5$ for num$\_$items, $23\mathrm{.}5$ for total, $4\mathrm{.}7$ for average, $10$ for maximum and $0$ for minimum.

Expected output values for each variable

Variable Value

num$\_$items $5$

total $23\mathrm{.}5$

average $4\mathrm{.}7$

maximum $10$

minimum $0$

Now, create a second Statistician object s$2$ and call the next$()$ function to insert $1,2,$ and $3$

s$2.$next$(1)$;

s$2.$next$(2)$;

s$2.$next$(3)$;

Then add the first Statistician object to s$2$ and save the result in the third Statistician object.

Statistician s$3=$ s$1+$ s$2$;

Display all of the values for Statistician s$3.$ These are the values you should see:

Total: $29\mathrm{.}5$

num$\_$items: $8$

maximum: $10$

average: $3\mathrm{.}6875$

minimum: $0$
