Write a program that prompts the user to input a sequence of characters and outputs A, E, I, O, U, and Y and the number of times each vowel appears in the input string.The program should include 3 functions: A null-return function, inString, that prompts the user to input a sequence of characters. User input should be stared in a string data type variable. A value-returning function, isVowel, that returns the value true if a given character is a vowel and otherwise returns false. A null-return function, outVowels, that outputs (to the console) a list of each vowel and the number of times that vowel appeared in the input sequence. Do NOT use global variables. Place as little code as possible in the main() function.
