In this assignment you’re going to write a complete C program
that opens a file “digits.txt”, inputs the values, and analyzes
these values to see if they follow Benford’s law. In particular,
your program analyzes the first digit of each input value, and
outputs: 1. The total # of input values N 2. The counts for each
digit: # of values that start with 1, # of values that start with
2, etc. 3. A histogram of the counts for...
