PLEASE HELP $ME$ SOLVE THE PROBLE, THE TOPIC $IS$ TOO LONG $SO$ I HAVE $TO$ TYPE $IN$ QUESTION, PLEASE READ $MY$ WHOLE QUESTION AND WRITE CODE $INC$ COMPLETE, THANK YOU

Build a vending machine

To complete this project, you may work alone or with one other student in this section.

All coding must be completed and submitted by the end of class.

Your program must use the data in the configuration file $($vending$-$config.txt$)$

The first line of the file indicates how many coins of each denomination $($U$.$S$.)$ are provided, e$.$g$.$:

$100300200500$

Indicates that the machine has $100$ quarters, $300$ dimes, $200$ nickels, and $500$ pennies. The vending machine will

not be configured to hold more than $10,000$ coins of a given denomination.

The values for each type of coin are the standard, in US dollars: $0\mathrm{.}25$ for quarters, $0\mathrm{.}10$ for dimes, $0\mathrm{.}05$ for nickels,

and $0\mathrm{.}01$ for each penny.

The second line in the configuration file gives a count of how many different items are for sale in the vending

machine, e$.$g$.$:

$4$

The third line onward each include four entries per line: a two$-$letter code indicating the slot for the item, the

name of the item for sale, its cost in dollars, and the amount of each item. There will not be more than $200$ items

of any given type.

For example:

In a given configuration, the name of an item will not exceed $50$ characters.

Please pay attention to these requirements:

There is no predefined limit on how many different items are on sale in a given vending machine. This must

be dynamically allocated at run time.

The vending machine does not accept any payments over $$5\mathrm{.}00.$ If more than this amount is attempted, the

purchase is rejected due to overpayment.

Once the vending machine is configured, your code must output the initial state of the vending machine,

including which items it has for sale and all details for them and how many coins of each denomination it has.

Following configuration, your code must process the purchases.txt file, which has a collection of entries

indicating a two$-$letter code for an attempted purchase and the amount of money paid.

An example of some lines of input are as follows:

$A22\mathrm{.}50$

$B11\mathrm{.}78$

$Z9-6\mathrm{.}00$

$A140\mathrm{.}00$

Note: for these purchases, assume that a gift card $is$ being used $--$ the vending machine does not collect any coins $at$ all, $it$ merely consumes the amount $on$ the card, and dispenses change.

More requirements:

Processing must include $logging$ the results $of$ each attempted purchase $to$ a text file, vending$-$out.$txt.$ For each purchase, the $log$ must include the item code, nam, cost, amount paid, and other results.

$IN$ the case $of$ a rejected purchase, output the status $in$ a human$-$readable format; $in$ cases where a purchase was successful, include output $of$ coins returned.

Each purchase attempt results $in$ exactly one these statuses based $on$ processing:

$\frac{1}{i}f$ the amount paid $is$ less than the cost, $log$ "insufficient$-$funds"

$\frac{2}{i}f$ there are $no$ more items reamaining, $log$ "insufficient$-$supply"

$\frac{3}{i}f$ the code entered $is$ invalid, $log$ "invalid$-$code". The code check should $be$ case$-$insensititve, $i.e.$ lookup for $"A5"is$ the same $as"a5"$

$\frac{4}{i}f$ the amount paid $is$ over the $limit,log$ "over$-$payment"

$\frac{5}{i}f$ there $is$ not enough change $in$ the machine $to$ complete the purchase, $log"no-$change"

$\frac{6}{i}fan$ item $is$ successfully purchased:

$A.$ Indicate success

$B.$ report the amount $of$ change returned

$C.$ report how many coins $of$ each denomination are returned

$D.$ update the vending machine $by$

I. Removing one $of$ the items purchased

$II.$ removing amounts $of$ couns returned $as$ change.

III. Incrementung a total number $of$ items sold

$IV.$ adding the amount $of$ the purchase $to$ total sales.

$At$ the start and end $of$ the $log$ file, your code must also $log$ the state $of$ the vending machine:

$\frac{1}{A}$ list each item for sale $by$ code and name and the amount remaining

$\frac{2}{a}$mount $of$ each coun remaining $in$ the system

$\frac{3}{t}$otal amount $of$ sales

$\frac{4}{a}$ count $of$ how many purchases were attempted

$\frac{5}{h}ow$ many purchases were successful

$\frac{6}{A}$ count and histogram $by$ percentage $of$ successful purchases $by$ product

$*$ Note that the sum $of$ counts for requirement $6$ must $be$ the same $as$ the count $in$ requirement $5$

Refer $to$ vending$-$out.$txt$ for $an$ example $of$ acceptable program output.

$At$ a minimum, your program should report the following steps $to$ stdout:

$-$ loading the vending machine configuration

$-$ processing the purchases

$-logfil\frac{e}{p}$rogram complete

$At$ a minimum, your submission must include a main.$c$ file, a vending.$c$ file, and a vending.$h$ file. These files should contain code and type declarations $as$ appropriate. The main.$c$ should contain only preprocessor directives needed $to$ run the program and $an$ implementation $of$ the main$()$ function.

Your submission must include all header$(.h)$ and source$(.c)$ files needed $to$ compile and run the code.

You may include your vending$-$out.$txt$ file, but your grade will $be$ beased $onmy$ execution $of$ your code using different vending machine configurations and sets $of$ purchases.
