Write a function charInWord that takes in two parameters, a char (character) and a word (string). The function will return True if the character is in the word and False if it is not. If word is not a string type, or if char is not a string type, or if the length of char is greater than 1, the function should return None. Your main program should call the function and print char is in word if the function returns true, or char is not in word if the function returns false, using the user-supplied values instead of char and word. The program should print incorrect input provided if the function returns None.
