Question

Use the function isSeparator(c) above in writing a function that counts the number of words in a string. In your solution, consider different cases of the string, such as having few adjacent space characters, tab and newline characters. You may consider that words can be 1 or more alphanumeric character(s), an alphanumeric is either an alphabetical letter (lower or upper case) or a number Hint: The last character of a word is followed by a separator, a new line, or a null character.
