Question

Programming Project 3.15 asked you to explore Benford’s Law. An easier way to write the program is to use an array to store the digit counts. That is, count[0] might store the number of times 0 is the first digit (if that is possible in your data set), count[1] might store the number of times 1 is the first digit, and so forth. Redo Programming Project 3.15 using arrays.

Write a program that tests Benford’s Law. Collect a list of at least 100 numbers from some real-life data source and enter them into a text file. Your program should use an array to store the digit counts. That is, count[0] might store the number of times 0 is the first digit (if that is possible in your data set), count[1] might store the number of times 1 is the first digit, and so forth. For each digit, output the percentage it appears as the first digit.
