A laundry shop offers washing service to its customers. It welcomes its customers every day to bring their laundry

in or take it out after its being washed. The shop has only one washing machine that takes only $5$ pieces of

clothing at a time. Once customers bring their clothing, the shop worker starts stacking it in small boxes that he

queues $($the order of clothing in one box does not matter, the order of boxes is what matters$).$ See the figure

below for illustration. If the box is full it will be loaded into the washing machine, but if the machine is full, a new

empty box is used and queued.

Implementation $(70$ points$)$:

A$.$ Define a simple data type $($struct$)$ for clothing that has only three public member variables id$,$

cost$,$ and owner. The id is a unique integer given for each clothing for identification. The cost is a

float number for the cost of the laundry. Finally, owner is a string to store the name of the owner. Save

the clothing struct in a header file and include it in linkedQueue.h file. $[4$ points$]$

$$ To help you: The header file is created for you; you only need to insert the struct definition of

clothing $(4$ lines of code!$).$

B$.$ To store the clothing for the next wash, a stack of clothing $($a list or a queue will do$,$ but they are too

fancy for such a purpose since no need for their extra functionalities at all$).$ The stack maximum size must

be $5$ as you can tell from the specifications above.

$$ To help you: The file $$mystack$.$h$$ is changed so every time a stack is created using the default

constructor then the maxStackSize is set to $5.$

C$.$ To maintain order for the stacks, define a queue of stacks, let us call it any queue of stacks of clothing Q

to make our explanation smoother.

$$ To help you: The queue Q of stacks is defined for you in the main$()$ function in the file called

solution.cpp in which you will add the functions described in E$,$F$,$ and G below.

D$.$ Add a member function $($call it addClothing$)$to the class linkedQueueType. This function has a

single parameter of type clothing. The function adds the clothing to the last stack in the calling queue,

if the stack is full, the clothing will be added to a new stack that is added to the rear of the calling queue.

If the calling queue is empty, the same from previous case must occur. $[16$ points$]$

E$.$ Add a non$-$member function $($call it wash$)$ that simulates washing a batch from Q$.$ This function takes Q

as a parameter, it empties the first stack from Q $($into the washing machine$)$ and remove it from Q$.$ If Q is

empty, the function gives the message $($There is nothing to wash!! Have a nap, or start

marketing!!$).$ If the first stack in Q is not full $($has less then $5$ pieces of clothing$),$ the function gives the

messages $($The only batch is not full, let us wait!$).$ otherwise, the function prints the washed

clothing. $[16$ points$]$

F$.$ Add a non$-$member function $($call it print$)$ that takes Q as a parameter, prints the details of Q$.$ If Q is

empty, the function gives the message $().$ Otherwise, the function will print the details $($id$,$ owner,

price$)$ for each clothing piece in each stack in Q$.$ After that the function prints the number of stacks in Q$.$

$[16$ points$]$

G$.$ Add a non$-$member function $($call it bill$)$ to show the bill for a customer by his$/$her name. This function

takes two parameters: Q$,$ and the name of the customer$($string$).$ If Q is empty, a message stating that

must be shown. Otherwise, the function must summon the prices for all pieces of clothing owned by the

customer in every stack of Q in the following form $($The customer Ali has $4$ clothing piece$($s$)$

that cost$/$s $4\mathrm{.}05).$ For customer with nothing in the queue, it is fine to have zeros in the count of

pieces or the total cost. This function MUST NOT CHANGE Q neither by contents nor by nature $($queue$)$;

therefore, it is recommended to have a copy of Q inside the function, and empty the copy not the

parameter. $[18$ points$]$

How to start:

$1.$ Download the compressed file $($start$.$rar$)$ from Moodle, then extract it$.$ It will result in a folder with $6$

files: clothing.h$,$ linkedQueue.h$,$ solution.cpp$,$ myStack.h$,$ queueADT.h$,$ and

stackADT.h$.($The files in red are not to be touched!$).$

$2.$ In the file clothing.h$,$ add the definition of struct clothing as specified in $($A$)$ above to get $4$

points.

$3.$ In the file linkedQueue.h$,$ add an implementation for addClothing function as specified in $($D$)$

above. Remember that you need to add its prototype inside the class, and its definition outside the class.

This will get you $16$ points.

$4.$ In the file solution.cpp$,$ do the following:

a$.$ To get $16$ points, add the non$-$member function wash as specified in $($E$)$ above.

b$.$ To get more $16$ points, add the non$-$member function print as specified in $($F$)$ above.

c$.$ Finally, to get the last $18$ points, add the non$-$member function bill as specified in $($G$)$ above. using c$++$ language
