std::bitset has a to_string() method for serializing as a char-based string of 1s and 0s.Obviously, this uses a single 8 bit char for each bit in the bitset, making the serialized representation 8 times longer than necessary. I want to store the bitset in a binary representation to save space. The to_ulong() method is relevant only when there are less than 32 bits in my bitset. WebFrom the above picture, the bit position 2 (bit value 1) in binary number representation occupies the third lot counting from the right side.
