For this C++ programming problem, you will write exactly 3 functions:

Write a value-returning function called isVowel that takes a character as a parameter and returns true if that character is a vowel and false otherwise.

Write a value-returning function called countVowels that takes a string as a parameter and returns the number of vowels contained in that string. This function should call the isVowel function described above.

Write a main function that prompts the user to input a line of text and outputs the number of vowels in that line of text. Your main function will call the countVowels function described above.

You will implement all 3 functions in the same file
