Container Class vs Class - C

Question

I'm new to programming and have only now discovered this assignment.

I've looked on the internet and in my book, but I still don't understand the difference between a Container Class and a Class in C++.

How could I make a family class with 20 individual objects all at once?

Answer 1

"Container class" is not an official phrase; it is simply the word "class" followed by an English description word. 

The assignment requires you to construct a class that holds some extra data, namely an array of 20 human instances.

At its most basic, the outcome may be as follows:

class family
{
public:
   person people[20];
};

Instead, in real life, you may do something like this:

#include <array>
using family = std::array<person, 20>;

Because it is doubtful that every family (or even most families) has exactly 20 members, I would personally settle for:

#include <vector>
std::vector<person> family;

… and modifying the vector as needed
