C++

Write a program that will read in a line of text (use the getline function) into a string variable and output the number of words in the line and the number of occurrences of each letter Specifications: Define a word to be any string of letters that is delimited at each end by either whitespace (not just the space character!), a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and all forms of punctuation. When outputting the number of letters that occur in a line, be sure to count uppercase and lowercase versions of a letter as the same letter. Output the letters in alphabetical order in uppercase and list only those letters that occur in the input line If you execute the program, the following information should be displayed: ~> main . Enter a Line of Text: I say ' Hi!". Words:3 Letters
