Keep in mind though, that [0] means the least significant bit, but we want to store them in the most significant -> least significant order, so we have to use the 7 - j instead of simply j:

WebBitset usually uses some underlying default integer for containing data. 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 - … WebApr 8, 2024 · One option is to use the "bitset" class, which is included in the "bitset" header. The "bitset" class provides a convenient way to work with binary data and can be used to convert a binary string to an integer. Conclusion: Converting a binary string to an integer in C++ is a relatively simple task.
