That one wasn't worded correctly either, I guess. Presumably you've tried cout << value; ?
If so how is that not what you want?

But I don't see how "how would you use cout to check a value" can be an explanation for "how do you swap the rows" when an answer to "how do you swap the rows" makes you realise that "how do you swap the rows" isn't what you meant.

I'm confused...
