Why is a char and a bool the same size in c++?

Question

I\'m reading The C++ Programming Language. In it Stroustrup states that sizeof(char) == 1 and 1 <= sizeof(bool). The specifics depend

Answer 1

Theoretically you only need a single bit for a bool, but working with less than 1 byte's worth of data is messy. You need more instructions to achieve anything and you don't really benefit.

If you want to pack multiple booleans into a single byte you can use a bit-field structure.
