将bool转换为位序列

Question

寻找一些操作员(我猜是代替+？)

unsigned char bits = true + false + true + true + true;  // 1 byte is sufficient

成为以下位模式:

00010111

然后,我如何检查if中的位模式

if (bits == 00010111)

Answer 1

你要

bits = true << 5 | false << 4 | true << 3 | true << 2 | true << 1;

要么

bits |= true;
bits <<= 1;
bits |= false;
bits <<= 1;
bits |= true;
bits <<= 1;
bits |= true;
bits <<= 1;
bits |= true;
