c++binarybyte

Is directly putting in a binary number possible C++?

Is putting in binary as a value possible?

I want something like char test = 00101011, and it will become 43. I know this is possible by making a function that converts binary to decimal (which can be inputted), but that’s not direct, and I’m pretty sure it takes time.

Solution

  • You need to put the prefix 0b.

    #include <iostream>

int main()
{
    char c = 0b00101011;
    std::cout << static_cast<int>(c) << std::endl;
}
