Using C++ write this code Write a function called isValidNote that accepts a string and returns true if that string is a valid note expressed in SPN and false otherwise. See the explanation above for clarity on what is and is not considered valid SPN. Function Specifications: Name: isValidNote() Parameters (Your function should accept these parameters IN THIS ORDER): note (string): The string to be checked Return Value: True or false (bool) The function should return true if the string is a valid note in SPN and false otherwise. The function should not print anything. The function should be case-sensitive, e.g. B0 is valid SPN but b0 is not. Hint: Any note expressed in valid SPN will be exactly 2 characters long. --- Examples --- Sample function call Expected return value isValidNote("y") False isValidNote("D4") True isValidNote("d4") False isValidNote("E72") False isValidNote("I love coding") False Your file should be named isValidNote.cpp and should also…

Problem D. Durdle Game Using the function from the previous problem, write a function durdle_game(target) which takes in as an argument a single string that will be the target to guess, and lets the user attempt to guess the target word. Each time the user makes a guess, the function will print out the result of the previous function to tell the user how close they are. If the user guesses correctly, then the game is over. Have the function return the number of guesses that it took the user to get the correct answer. Examples (text in bold is returned, text in red is user input.): >>> durdle_game('trick') Welcome to Durdle! Enter a guess:touch GBBGB Enter a guess:trash GGBBB Enter a guess:truck GGBGG Enter a guess:trick GGGGG Congratulations, you got it in 4 guesses! 4 >>> durdle_game('stoop') Welcome to Durdle!

Complete the check_strings_same_start(word1, word2) function which is passed two string parameters. The function returns True if the two parameter strings start with the same character and only one (not both) of the parameter strings has an even number of characters (including any space characters), otherwise the function returns False. For example: Test Result result = check_strings_same_start("blue", "bag") True print(result) print(check_strings_same_start("babyproofing", "baby")) False print(check_strings_same_start("check", "fact")) False
Ex. 8.4) The following functions are all intended to check whether a string contains any lowercase letters, but at least some of them are wrong. For each function, describe what the function actually does (assuming that the parameter is a string).
