So in your case bitset<1>, bitset<32>, bitset<64> will be of the same size. Using such an integer is definitely more efficient for larger bitset sizes - for variety of reasons - but I cannot say much for size of 8.

I've got the task to create a graph's adjacency matrix from a list of adjacent nodes, stored in a file (don't need the weights) into a bitset array in C++. I successfully read the adjacent nodes from the file, but when I try to store it in the bitset array the outcome is not right. My function is the following: WebJun 2, 2015 · I take each char of the string and convert it to binary value through the use of bitset. e.g. bitset <6> b1 = s[0]; //a bitset <6> b2 = s[1]; //b bitset <6> b3 = s[2]; //c then i want to put the results into an array of strings. The name of the array is arr (and each string of the array will represent the binary value of each char) e.g

WebBitSet has several problems:. the length of the byte array it provides on output, using .toByteArray(), depends on the uppermost bit set to 1 (0 if no bit set, 1 if the last bit set is < 8, 2 if < 16 etc -- in essence, indexOf(highestBitSet) + 7) / 8);; as such, you cannot rely on it for computing a bit mask of fixed length. Consider using a wrapper over ByteBuffer instead.
