Task: Create And Display New Password Using Rules

Rules:

Rule 1: Replace all of the vowels (A, E, I, O or U) in the original password with a number as follows: (20 points) Replace the first vowel with the number of 1. Replace the second vowel with the number of 2. Replace all other vowels with the number of 9.

Rule 2: Replace all of the numbers in the original password with the letter Z. (15 points)

Rule 3: Reverse all of the characters in the original password. (10 points)

Rule 4: The enter password should be non case-sensitive. All the letters in new password should be in upper-case. (5 points)

This is what is should look like:

My code:

CODE:

Right now I'm not worried about the efficiency of the code (i.e. simplifying code into fewer lines). The problem I am having is the locating and replacing of the vowels. When running the program the code will replace all of the numbers with "Z", reverse the string, and make all letters uppercase. When it comes to locating the vowels, the program squares the number it goes through the string by the number of letters that it contains. I don't know why it does this.

when the string contains more then 1 vowel the first time it goes through it replaces all vowels with 1, then goes through again and replaces all vowels with 2, and goes through again repalcing all vowels with 9. These are all then combined into one string.

The research I have done has only turned up how to replace vowels with one thing (i.e. all vowels become "*")
