Question

I want to create in C++ an array of Objects without using STL.

How can I do this?

How could I create array of Object2, which has no argumentless constructor (default constructor)?

Answer 1

If the type in question has an no arguments constructor, use new[]:

Object2* newArray = new Object2[numberOfObjects];

don’t forget to call delete[] when you no longer need the array:

delete[] newArray;

If it doesn’t have such a constructor use operator new to allocate memory, then call constructors in-place:

//do for each object
::new( addressOfObject ) Object2( parameters );

Again, don’t forget to deallocate the array when you no longer need it.
