I have recently learned something and now I am posting it here as a challenge to anyone. The rules are simple: All answers must please be ROT13 encrypted.
The challenge: You have two ints x and y you have put the contents of x into y and vice verse, you may not use: pointers, another variable. Your code may only be on one line (';' terminates a line).
Please let me know of any errors and please ENCRYPT YOUR ANSWERS.
Your ROT13 code isn't correct; it isn't supposed to be applied to numbers or punctuation. Also, the idea of ROT13 is that you use the same program to encrypt and decrypt. To do that, you need to check whether each character is greater than 13th in the alphabet or not.
