Using the dictionary of four letter words write a program that will check a sequence of 4 characters entered from the keyboard to determine if it is a word.
Your program should have a function that employs a binary search to look for the word. All words must first be read from the file and stored into an array.
There are 4030 words in the dictionary. Your output should indicate whether the word is valid or not. Count the number of comparisons and print that to the screen along with the validity of the word.
