Yesterday my father taught me how to use a dictionary. It's pretty handy to use.

Yeah, I wish a lot more people around here could use a dictionary!

I meant in programming.
You can use it to make the program remember things and what he has to do when he sees it.
example: Dictionary<string, string> questionAndAnswer0 = new Dictionary<string, string>();
questionAndAnswer.Add("-Key-", "-Value-")
if (questionAndAnswer.ContainsKey(answer0))
Console.Writeline[answer0];

I made a few mistakes, but this is what i meant.
(It's C#)
