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

C does not have native notation for pure binary numbers. Your best bet here would be either octal (e.g. 07777) of hexadecimal (e.g. 0xfff).
