Line 96:
GCC supports specifying integers in binary using the [http://gcc.gnu.org/onlinedocs/gcc/Binary-constants.html 0b prefix] syntax, but it's not standard. Standard C has no way of specifying integers in binary.
To specify a literal of an unsigned integer, you add the suffix "u" or "U". To specify a literal of a "long" integer, you add the suffix "l" or "L". In C99, to specify a literal of a "long long" integer, you add the suffix "ll" or "LL". (The "l" and "ll" forms are discouraged as "l" looks like the digit "1"). The "u" suffixes can be combined with "l" or "ll" suffixes for unsigned long or unsigned long long integers.
