Practicing Methods

The code contains a struct called Cypher which basically represents a kind of Caesar cipher.

Read the code and fill in the blanks to make sure it works properly. The following is how the final program is supposed to be:

1. setText method converts the passed text into encoded text and stores it into the field text. This method takes one stringargument calledtext`, and the method does not return any value;
2. rawText returns the text field content. This method takes no arguments;
3. decodedText decodes the text field content and returns the result. This method also doesn't take any arguments.
