I have the following in my Puzzle.h

class Puzzle
{
    private:
        vector<int> puzzle;
    public:
        Puzzle() : puzzle (16) {}
        bool isSolved();
        void shuffle(vector<int>& );
};

and then my Puzzle.cpp looks like:

Puzzle::Puzzle()
{
    // Initialize the puzzle (0,1,2,3,...,14,15)
    for(int i = 0; i <= puzzle.size(); i++)
    {
        puzzle[i] = i;
    }
}

// ... other methods

Am I using the initiailizer list wrong in my header file? I would like to define a vector of ints and initialize its size to that of 16. How should I do this?
