can you make something smaller than 1 byte?
hello,
when i started learning c++ i was taught that the smallest variable you can make is a char which uses 1 byte to store its information.
however i just learned about something called a "nibble" which uses 4 bits instead of 8
so i was wondering if it was possible to make a variable use a "nibble" instead of a byte to make it use even less memory?

You might want to take a look at this, "Storing a nibble (4 bits) at a memory location"

Sounds like you might want to read up on bit fields.

Peter87, excellent reference. Thanks for pointing it out so I can peek at it.
