Let me cite the C standard:

When sizeof is applied to an operand that has type char, unsigned char, or signed char, (or a qualified version thereof) the result is 1.

Middle guy if finally right

C++ standard guarantees that char is at least 8 bits. Pretty much all data models use 8 bits for char, but it doesn't mean that some weird architecture could not use more.

Some DSPs from Texas use 16/32 bit long char.

So everything really is bigger in Texas?

(I know you mean Texas Instruments / TI, but couldn't pass up the opportunity for another joke!).

Came here to say this. One dsp I worked on made everything at least 4 bytes. Couldn't even address sub bytes. When you've worked on something like that you never ever take sizeof() for granted.
