WebJul 24, 2024 · If you're using C++, then use C++ features (like cin / cout ). You can use to_string then print out its char array. You cannot use scanf directly with bitsets, because scanf requires an address to a byte, not a bit. However, you can first use scanf to write to a byte ( unsigned char) or an int and then convert it to bits for the bitset.
