WebQBitArray uses 0-based indexes, just like C++ arrays. To access the bit at a particular index position, you can use operator [] (). On non-const bit arrays, operator [] () returns a reference to a bit that can be used on the left side of an assignment. For example: QBitArray ba; ba.resize(3); ba[0]=true; ba[1]=false; ba[2]=true; WebC++ Utilities library std::bitset Converts the contents of the bitset to a string. Uses zero to represent bits with value of false and one to represent bits with value of true . The resulting string contains N characters with the first character corresponds to the last ( N-1 th) bit and the last character corresponding to the first bit. how to fill in beard
