# 42Old-CPP_Module_04
## ex03
- Abstract and Interface
- interface は `can-do` 関係，abstract は `is-a` 関係．
- Interface とは，純粋仮想関数だけで構築された Abstract class の特別なバージョンのこと．
- Interface は，can-do 関係と呼ばれる関係性を構築する．
- Interface は，そこから派生したクラスが「何ができるか」を表現するもの．
## ex02
### Abstract class
- > Defines an abstract type which cannot be instantiated, but can be used as a base class.
- [abstract class](https://en.cppreference.com/w/cpp/language/abstract_class)

### Shallow copy and deep copy
- [13.16 — Shallow vs. deep copying](https://www.learncpp.com/cpp-tutorial/shallow-vs-deep-copying/)
## ex00
### Virtual function
- [virtual function specifier](https://en.cppreference.com/w/cpp/language/virtual)
### explicit
- > Specifies that a constructor or conversion function (since C++11) or deduction guide (since C++17) is explicit, that is, it cannot be used for implicit conversions and copy-initialization.
