Recall in program #$1,$ you controlled your loop using while$(($c$=$getc$($fp$))!=$EOF$).$ In this

assignment, you will control your while loop in the same way but rather than calling getc, you

will call your own input function. That function will return the result of fscanf, which itself will

be the number of inputs. This value is EOF if you have reached the end of the file. From main$$s

while loop, the code looks like while$($input$(...)!=$EOF$)\{...\}$ where $...$ is the parameter

list. You will have to figure out how to pass these parameters. One of the parameters will be your

FILE $*$ variable.

The while loop$$s body will contain all of your function calls to the various computation functions,

output and update. DO NOT include any other code in the loop body. The idea is that main is

almost entirely a set of function calls. For instance, do not add $1$ to the number of cities in the loop

or use an if statement in the loop to determine if this city is more livable than the previous most

livable. After the loop, you will call the summary function.

Below are the formulas you will use for your various computations. All of the results should be

doubles $($or floats$).$ Keep in mind that population and square mileage are ints so you will need an

appropriate cast in the first equation to force a double$/$float division instead of an int division.

$$ Population density $=$ population $/$ square mileage.

$$ Pollution rating $=$ pollution amount $*$ population density $/1112\mathrm{.}2$

$$ Traffic rating $=$ population density $*1\mathrm{.}7/$ major highways

$$ Crime rating $=$ crime $*$ population density $/872\mathrm{.}6$

$$ Expense rating $=$ expense $*$ population density $/1617\mathrm{.}1$

$$ Livability $=100($Pollution rating $+$ Traffic rating $+$ Crime rating $+$ Expense rating$)/$

$13\mathrm{.}81$

The values $1112\mathrm{.}2,1\mathrm{.}7,872\mathrm{.}6,1617$ and $13\mathrm{.}81$ should all be constants defined using #define.

Do not hardcode any of the numbers in the actual assignment statements $($aside from $100).$ Create

useful names for these constants to promote readability in your program. If your names are not

good, provide comments to explain the role of each constant.

Organize your program in separate files as follows:

$1.$ the main function in a file by itself

$2.$ the functions from $2,6$ and $8$ in an input$\_$output file

$3.$ the functions from $3,4,5$ and $7$ in a computation file

$4.$ a header file that includes all function prototypes, all #include statements $($aside from

the #include for your header file$)$ and all #define statements; there will be no C code

in your header file and the three $.$c files will only have one #include for your header file

If you are confused about how to write your code, see the example programs on the sample code

website, particularly the payroll and craps examples.

NOTE: in Visual Studio after creating a project, in the right pane in the Solution Explorer window,

expand this and you will find entries for Header Files and Source Files $($also Resource

Files$).$ Right click on Source Files and select Add and then either New Item to create your

header file or Existing Item and add your $.$c files. Load already written files if you have

written them elsewhere. Repeat this for Header Files to create or add your header file into the

project.

Along with this assignment description are two data files, cities$1.$txt and cities$2.$txt$.$ Run your

program on cities$1.$txt to compare your results to those shown below. Once you have your program

running correctly, run it on cities$2.$txt$,$ copy and paste the output to the bottom of your main.c file.

You do not need to submit your output from cities$1.$txt$.$ What follows is my output. You should

get similar numbers and have your output formatted in a readable way although it does not have

to precisely match this version.

City Livability Pop Density

Akron $66\mathrm{.}42389\mathrm{.}14$

Cincinnati $71\mathrm{.}77449\mathrm{.}88$

Cleveland $52\mathrm{.}67660\mathrm{.}58$

Columbus $51\mathrm{.}29709\mathrm{.}69$

Dayton $65\mathrm{.}77532\mathrm{.}97$

Toledo $60\mathrm{.}64427\mathrm{.}23$

Of $6$ cities, the average livability is $61\mathrm{.}43$

The most livable city is Cincinnati with a livability of $71\mathrm{.}77$

Remember to comment your code well. Every function should have its own introductory comment

$($the main introductory comment should be in main.c for main$$s introduction, along with your

name$).$ Also command your prototypes to explain the role of each function $($you can use the same

comment for each of these as your function intro comments$),$ and comment the logic and usage of

variables, etc, like you did or should have for program $1$
