Question

I think the title is clear on explaining my problem…. consider the following snippet:

class Critter {
    int m_Age;
};

int main()
{
    vector<Critter* const> critters;
    for(int i = 0; i < 10; ++i)
        critters.push_back(new Critter());

    critters[2] = new Critter();

    return 0;
}

Shouldn’t the line critters[2] = new Critter(); be illegal?

Thank You

Answer 1

Actually this line should be illegal (even given #include <vector> and using std::vector;):

vector<Critter* const> critters;

Because it is a requirement for a type to be used in a container to be assignable and anything that is const clearly isn’t.
