Integer constants can be written as binary constants, consisting of a sequence of `0' and `1' digits, prefixed by `0b' or `0B'. This is particularly useful in environments that operate a lot on the bit-level (like microcontrollers).
The following statements are identical:
i = 42; i = 0x2a; i = 052; i = 0b101010;
The type of these constants follows the same rules as for octal or hexadecimal integer constants, so suffixes like `L' or `UL' can be applied.
