How to get the properties of an object?
The object could be one of three different types and will have a set of public properties.

For example, instead of creating 100 integer variables, you can create an array that stores all of those integers!

What is a C++ dynamic array?
A dynamic array is quite similar to a normal array, but its size can be changed during program execution time. The elements of the DynamArray occupy a contiguous block of memory. Once an array has been created, its size cannot be changed. A dynamic array can expand in size even after it has been filled.
