Question

C++ PROGRAMMING

Implement a bool function whose header is given below. Inside the function, declare, ask, and get a character from the user. The function will return true if the character the user enters is NOT in either of the words, otherwise it will return false. Keep in mind that uppercase and lowercase letters are not the same. You will need to change both words and the character input by the user to the same case (upper or lower) - Use the toupper or tolower function from cctype, remember that this function changes one character at a time. bool LetterinWord(string word1, string word 1); //precondition: two strings have values //postcondition: returns true if neither of the strings have the character that is input //by the user Example, the function would return true for the following: Character input by the user:'p word1: today, word2: tomorrow -no 'p' in either word Example, the function would return false for the following: Character input by the user: 'p' word1: happy, word2: excellent Character input by the user: 'p' word1: happy, word2: COMPUTER
