Ok so i have a class Vector:

#include <cstdlib>

class Vec
{
private:
    size_t size;
    int * ptab;

public:
    Vec(size_t n);
    ~Vec() {delete [] ptab;}

    size_t size() const {return size;}
    int & operator[](int n) {return ptab[n];}
    int operator[](int n) const {return ptab[n];}

    void operator=(Vec const& v);
};

inline Vec::Vec(size_t n) : size(n), ptab(new int[n])
{ }

and the problem is that in one of my homework exercises i have to extend constructor def, so all elements will be initialized with zeros. I thought i know the basics but cant get through this dynamic array -.-

ps. sry for gramma and other mistakes ;)
