Meaning of U suffix
I'm going through code that has a bunch of defines that look like: #define HEX_NUMBER (0x000000FFu)
What is the trailing u? I've tried compiling with and without it and I don't see any difference.

Thought the same, but case is different so I didn't follow thru. lower case is different enough for me in case sensitive C/C++ land. – Michael Dorgan Dec 14 '11 at 18:39

@MichaelDorgan, the linked question has a relevant comment about the casing. – zneak Dec 14 '11 at 18:41

Appending u to any integral constant makes the compiler interpret it as unsigned.

2"interpret" is a bit misleading. What's happening is that the *type* of the literal expression is an unsigned type. – Kerrek SB Dec 14 '11 at 18:45
