[BDAY] unsigned char age = age++;

Today happened to be my birthday, we just need an unsigned char to represent age, can you tell whats wrong with the code in the title (or below?).

static unsigned char age;

void Birthday(){
  age = age++;
}

Looks like the Standard 'C' says the value in the age is undefined ? because the assignment (=) is not a sequence point where the side effects (++,--) are settled. That can make the age of the person remain the same or increase it by one its ambiguous.

Cheers!
