initialization is now part of the declaration, rather than a separate statement, the identifier can be a constant. For example:

const std::string s = b ? "foo" : "bar";

Case selector

The conditional operator can be used for case selectors. For example:

vehicle = arg == 'B' ? bus : arg == 'A' ? airplane : arg == 'T' ? train : arg == 'C' ? car : arg == 'H' ? horse : feet;
