I've built a class, one parent and multiple children, that I need to group together to eventually be stored in a single file. For the moment I've gone with something like this:
This compiles, and using "group[0]." calls the variables and methods from the class, which also compiles. But what I can't seem to access is the constructor. My class has both a blank default constructor and the standard initialized all variable constructor, the latter which I want to use. However, "group[0]." does not bring up the constructor option, and "group[0]()" does not compile. So how do I use my constructor?

This is where the C memory functions fall flat, they don't work well with constructors and destructors. I recommend ditching calloc and using new[]:
Or better yet, use the vector container class if you plan on resizing the collection:

I'm a programmer. My attitude starts with arrogance, holds steady at condescension, and ends with hostility. Get used to it.

The calloc (and malloc) function never calls constructors; free() never calls destructor(s).
So using new and delete operators for class objects (or array of class objects) is not only recommendation or a good style symptom - it's one of the very strict C++ language specifications.
