I have a binary string in a file that looks like
0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001100100101101100110000110100110110111000010100110110110110111000011001000010110010010001100010010001010010010100001011001100010100001100100011011101
(which is 256 bits). Can I set this string as the value of a bitset<256>
really quickly?
Currently I am doing
for (int t = sizeof(c) - 1; t > 0; t--) {
if (c[t] == '1') {
b |= 1;
}
b <<= 1;
}
b >>= 1;
But my results are incorrect.

Yes, you can just use the constructor, the example below is taken right from the document and works for 256
as well:
std::string bit_string = "110010";
std::bitset<8> b3(bit_string); // [0,0,1,1,0,0,1,0]
std::cout << b3.to_string() << std::endl ;
Why not access the by indices directly? like..
b[t] = c[t] - '0';
