Random Non Repetetive Numbers
This program fills an array[20] with random numbers between 1 and 20, without repeating a number. This code can be used for encryption, games, testing software and much much more. give me some credit if you use it, and if you like it vote.. if you change it, please send me the updated version. thanks for downloading it.
