Question

I have simple class with width and height member fields which define number of rows and columns in matrix. I have matrix representation (0nly 0 and 1 needed) like bitset<> fields ( I included ) and I want to set size of bitset field in constructor.

Matrix(int w, int h)
{
    // fields to have size w*h
}

private:
    int width;
    int height;
    //bitset<unknown at the moment> fields;

Is possible to achieve this ?

Answer 1

std::vector<bool> does exactly what you need, with 1 bit per value.

Alternatively you can use boost::dynamic_bitset (I think it was called).
