This assignment involves writing a C++ program to identify and count lines, words, and characters. For the purpose of this assignment, we define a \"word\" as a sequence of characters that are not whitespace characters. Words are delimited by one or more whitespace characters. A whitespace character, such as a space, tab, or newline, is any character for which the
