Saving a Huffman Tree compactly in C++ -

let's i've encoded huffman tree in compressed file. have example file output: 001a1c01e01b1d i'm having issue saving string file bit-by-bit. know c++ can output file 1 byte @ time, i'm having issue storing string in bytes. possible convert first 3 bits char without program padding byte? if pads byte traversal codes tree (and codes) messed up. if chop 1 byte @ time, happens if tree isn't multiple of 8? happens if compressed file's bit-length isn't multiple of 8? hopefully i've been clear enough. the standard solution problem padding. there many possible padding schemes. padding schemes pad number of bytes (i.e., multiple of 8 bits). additionally, encode either length of message in bits, or number of padding bits (from message length in bits can determined subtraction). latter solution results in more efficient paddings. most simply, can append number of "unused" bits in last byte additional byte value. one level up, start

c++ - What's the result of a & b? -

this awkward, bitwise , operator defined in c++ standard follows (emphasis mine). the usual arithmetic conversions performed; the result bitwise , function of operands . operator applies integral or unscoped enumeration operands. this looks kind of meaningless me. "bitwise , function" not defined anywhere in standard, far can see. i , function well-understood , may not require explanation. meaning of word "bitwise" should rather clear: function applied corresponding bits of operands. however, constitute bits of operands not clear. what gives? this underspecified. issue of standard means when refers bit-wise operations subject of few defect reports. for example defect report 1857: additional questions bits : the specification of bitwise operations in 5.11 [expr.bit.and], 5.12 [expr.xor], , 5.13 [expr.or] uses undefined term “bitwise” in describing operations, without specifying whether value or object representation in view.
