WebSince the string length is a compile-time constant (the width of the type), you can just make a char buf [CHAR_BIT*sizeof (unsigned)]. Loop over it while you loop over bits in the integer, using a shift + mask. '0' + 1 is '1' for ASCII, UTF8, and any other sane character set, so you can do '0' + (n&1) to get a digit. – Peter Cordes raven warzone patch notes today
