/*
*DONE* Your program must prompt the user for a string of text using get_string.
*DONE* Your program should count the number of letters, words, and sentences
in the text. You may assume that a letter is any lowercase
character from a to z or any uppercase character from A to Z,
any sequence of characters separated by spaces should count as
a word, and that any occurrence of a period, exclamation point,
or question mark indicates the end of a sentence.
Your program should print as output "Grade X" where X is the grade
level computed by the Coleman-Liau formula, rounded to the nearest
integer.
If the resulting index number is 16 or higher (equivalent to or
greater than a senior undergraduate reading level), your program
should output "Grade 16+" instead of giving the exact index
number. If the index number is less than 1, your program should
output "Before Grade 1".
