Create a complete C program that includes all necessary functions in order to determine the

electricity costs associated with a certain apartment building in each area. Each apartment's

electricity consumption for the specified number of days is listed in a file named

ElectricConpumption.txt$.$ and the number of days related to each consume is contained in the file

Days.txt $($For instance, if the first line of ElectriicConsume.txt includes $157$ and the first line of

Days.txt contains $15,$ then $157$ Kilowatts of energy were spent over a period of $15$ days$).$ The

program's goal is to find out how much energy each apartment will cost based on how many

kilowatts are used and how much a kilowatt costs. The program's second objective is to calculate

each apartment's electricity consumption in KW using the average consumption of all units.

The program should use different functions, such as follows:

Function designed to determine each apartment's exact electricity costs before taxes depending

on the cost per kilowatt.

Function created to determine the exact fees after taxes by adding the tax value based on

consumption value to the amount of consumption reported on ElectricConsumption.txt$.$

Function designed to calculate the Approximate Electric consumption based on the total number

of days and total electric consumed for all apartments.

Function that indicates how the difference between exact and approximate data should be used to

define the percentage of error.

A specific file called ExactFeessBT.txt must include the values of Exact Fees before tax, which

represent the exact fees before tax for each apartment based on the calculation of electric

consumption and of each KW and the price of KW for category of consumption.

A specific file called ExactFeesAT.txt must be created to write the values of exact fees after tax

for each apartment, the value of each line in this file must specified for specific apartment based

on the exact fees before tax plus the value of tax based on the consumption value.

A particular file called ApproximateCons.txt will be used to store the values of approximate

consumption based on the total days for each apartment $($Each line in the file will be specified for

a specific apartment$).$ The approximation of consumption will be listed for each apartment based

on the number of days used to calculate fees.

The Value of Percentage Error for each apartment will be written to a specific file called

ErrorPerc.txt $,$ the percentage error can be calculated based on the equation below. Each line in
