WebSep 1, 2010 · 0. A bitset has a fixed number of bits. You specify bitset -- on most systems, CHAR_BIT is 8 so you will have an 8-bit bitset. When you try to stuff a bigger number into the bitset, the most significant bits are discarded. If you know in advance the largest numbers you will have to deal with, you can specify eg bitset<16> or bitset<32>.WebApr 28, 2015 · There is no guarantee that sizeof (bitset<8>) is 1. On my implementation, it happens to be 8. Thus, any assumption you are making about the internals of this class is just that - an assumption.
