Challenge: Understanding Uninitialized Variables

Link to the challenge:

Hello there.

Do you have a question?

If so, please edit your post to include it in the Tell us what’s happening section.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more information you give us, the more likely we are to be able to help.

Heed the advice of the comment and do not change any of the code under the comment:

// Only change code above this line

And in general, for any of these challenges, do not change anything unless specifically asked to. The tests don’t like it.

If you change the last line back to what it originally was:

c = c + " String!";

Then your code will pass.
