-Arrays help us to store and work with groups of data of the same type. The data is stored in consecutive memory spaces which can be accessed by using the name of the array and indexes or subscripts that indicate the position where the data is stored. Repetition structures provide us a simple way of accessing the data within an array. In today's laboratory experience you will practice the use of counters and one dimensional arrays to implement a program in which you will use Benford’s Law to detect files with bogus data.

-As part of your new job as IT auditor you suspect that someone in the Chicago Transit Authority (CTA) has been tampering with the information systems and changing the data files that contain the bus route daily totals. You are given five text files that contain daily totals for each of the CTA’s bus routes and must determine if one or more of the files contain bogus data. In this laboratory experience you will implement a program that will help you determine which of the file(s) contain bogus data using Benford's Law, a property that is observed in many real-life sources of data.

Text files consist exclusively of ASCII characters which represent data in any of the primitive types provided by C++. Typically, the values are separated by spaces. For instance lets asumme that the file `nameAge.txt` contains some data about names and ages.
