Create a simple class named Tally. Data members should include an array of 256 integer counters, for tallying occurrences of the 256 possible ASCII characters, a counter for the number of input characters, and an ifstream& for the input file. Define a constructor, a print function, and a “worker” function named doTally.
..... Write a main program that calls banner() at the beginning. Open the input file and use the open stream as a parameter to instantiate the Tally class. Call doTally(). Print the results of the tally.
