Question

Write a program which reads a String and displays the following output: Only the uppercase letters in the string. The string, with all vowels replaced by an underscore. The number of vowels in the string. The number of consonants in the string. The positions (indexes) of all vowels in the string. For the purposes of this program consider 'y' to be a consonant not a vowel. Input Validation: None required Requirements: Assume the string will have only uppercase and lowercase letters, and spaces. You are only allowed to use one for loop to solve this problem. No other loops allowed.
