> To be pedantic, a size of char is defined by CHAR_BIT in limits.h. As well as all of the min and max values and lengths in bits for integers. To be even more pedantic: it's the number of bits in a char that is defined by CHAR_BIT. However, sizeof returns the number of chars needed to store a type, where sizeof(char) is defined to be 1.
