You are working for a software firm that is to develop a word processor. In order to create an efficient spell checker, you want to know the frequency of occurences of vowels and consonants. Write a program which will prompt the user to enter a string from the keyboard. The program should then count and report the number of characters in the string. The program should also count and report the number of times each letter of the alphabet occurs in the string and print the percentage of the total represented. Using the principles discussed in finding the maximum element of an array, find the letter of the alphabet which occrus most frequently in the sentence. Find also the letter which occurs second-most frequently.
