For this computer assignment, you are to write and implement an interactive C++ program to scan and process a stream of words of a plain text Your program should start with an empty list of words. (Combinations of blanks, tabs, and newline characters to separate words.) After reading each word from the input stream, do the followings Check the word for punctuation marks. If the first letter of the word is preceded or its last letter is followed by punctuation marks, delete them from the word; however, if a word contains punctuation marks in the middle, ignore the letters beyond these punctuation marks. For example, if the word is fish, then the resulting word should be fish; however, if the word is fish net then the resulting word should still be fish. in 1. Use a map container to store the words, where each word is represented by a pair . The first element of the pair, named first, contains the name of the input word, and the second element of the pair, named second, contains its frequency in the input stream. To use a map container in your program, you need to insert the statement: #include
