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

Just use the standard library in C++:

#include 

You need a variable of type std::bitset:

std::bitset<8ul> x;
x = std::bitset<8>(10);
for (int i = x.size() - 1; i >= 0; i--) {
      std::cout << x[i];
}

In this example, I stored the binary form of 10 in x.

8ul defines the size of your bits, so 7ul means seven bits and so on.
