Can I use a binary literal in C or C++?

Question

I need to work with a binary number.

I tried writing:

const x = 00010000;

But it didn\'t work.

I know that I can use an hex

Answer 1

The "type" of a binary number is the same as any decimal, hex or octal number: int (or even char, short, long long).

When you assign a constant, you can't assign it with 11011011 (curiously and unfortunately), but you can use hex. Hex is a little easier to mentally translate. Chunk in nibbles (4 bits) and translate to a character in [0-9a-f].
