Question

Download the file USDictionary.txt from the course Blackboard site that contains words in the dictionary (about 118,000 words-all in lower case). Write a C++ program that will determine and the following items: The total number of words in the dictionary. The total number of characters in the dictionary (not including white space) The total number of characters in the dictionary (including white spaces) The total number of words ending in the letter e. The total number of 6 letter words. The total number of words beginning with a vowel. The total number of words containing the substring "ate" The total number of occurrences of the letter e. The total number of words containing at least two occurrences of the letter e. Turn in a printout of the program and the results.
