Removing the vowels from a sentence.

★☆☆

Disemvowelling is removing all the vowels from a piece of alphabetic text. It was once a common feature of the SMS language where the number of characters in a message was limited, and users were charged per message. It requires little cognitive effort to read so it was a good way of typing message quickly and keeping the cost down. Disemvowelling has more recently been used as a forum moderation tool.

Disemvowel

Make

Write a program that allows the user to enter a sentence before outputting that sentence with all the vowels removed.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the subprogram called dvowel that:

  1. Takes one parameter, message that is the string to process.
  2. Returns the message with all the vowels (AaEeIiOoUu) removed.

Complete the main program so that:

  1. The user can input the message to disemvowel.
  2. The dvowel function is called.
  3. The disemvowelled message is displayed.

Typical inputs and outputs from the program would be:

Enter the message: 
Hello world
The disemvoweled version of the message is:
Hll wrld

Enter the message: 
The quick brown fox jumps over the lazy dog
The disemvoweled version of the message is:
Th qck brwn fx jmps vr th lzy dg
