I just refer everyone to Tempest's post. Additional explanations of the mathematical meaning of a numerical base may be found in numerous other places. While it is true that time corrodes meanings, the corrosion is often the unfortunate work of, not time, but people of limited knowledge and vocabulary that can't find the proper expression on their tongue. They then adapt and, when questioned, proclaim their new discoveries, point to their academic credentials, and lead willing acolytes to kneel and kiss the hem of their robe. At that point we mere mortals are essentially lost.

"ASCII represents a single character in seven bits. For obvious reasons, each character takes up one byte with the most significant bit unused."
I think ascii codes are 8 bits and then its apear null('\0') pointer.
example
printf("%c,%d",'a',sizeof('a'));
answer is: a,8
but
printf("%d,%d",sizeof('a'),sizeof('\n'));
answer is: 8,8
______
its mean: |'a'|'\0'|
~~~~~
so i think ascii codes are 8 Bits or 1 byte or 2 nibles

don't mind because im just sharing my stupid knowladge

thanks

You are misconstruing things, biran. True ASCII is encoded in 7 bits. Yes, it occupies 8 bits much of the time, particularly in your memory. When it does, it's 'sizeof' is 8, but it still comprises only 7 meaningful bits. An ASCII character is a character. When you introduce the concept of a null ('\0') byte (which you are mistakenly calling a pointer), you are delving into territory dealing with a COLLECTION of characters. You should get your facts straight and not propagate your own misperceptions. I, for one, DO mind.
