Array with elements initialised with a non-default constructor was
considered and probably still is implemented by the gcc compiler but
finally the idea was given up to the concept of fill constructor in the
sequence types in the STL library. Check any STL documentation for
further details.
It is used like:
std::vector<int> v(5,3); // vector of 5 ints filled with the 3 value.
or
std::vector<int>* vp = new std::vector<int> (5,3);
