http://stackoverflow.com/questions/2670639/why-are-hexadecimal-prefixed-as-0x

the prevalent programming number systems were decimal and octal mainframes had 12 24 or 36 bits per byte which is nicely divisible.. by 3 log2 8 . The BCPL language used the syntax 8 1234 for octal numbers. When Ken Thompson created B from BCPL he used the 0.. words and all of the points above were still valid. Since octals were still needed for other machines 0x was arbitrarily chosen..
