Why bool is of size 1 byte ...and its only 1 or 0 so how its size became 1 bytes not 1 bit..???

Question

size of boolean value is 1 or 0 ??

Answer 1

A bool takes in real 1 bit, as you need only 2 different values. However, when you do a sizeof(bool), it returns 1, meaning 1 byte. For practical reasons, the 7 bits remaining are stuffed. you can't store a variable of size less than 1 byte.
