travenos / how_polymorphism_works

The project's goal is to show the concept, how one of the basic object-oriented programming (OOP) principles, a polymorphism, can work under the hood.

C++ Polymorphism Example

This project is created for educational purposes only.
The code might be interesting for C and C++ developers, who wonders how C++ classes really works behind the C++ syntax.
For example, it might help some developers to understand, what the key word virtual does.

The project's goal is to show the concept, how one of the basic object-oriented programming (OOP) principles, a polymorphism, can work under the hood.

The example is represented by two code pieces.
The first one (oop_cpp) is written in C++ and contains several polymorphic classes.
The second one (oop_c) is written in pure C. The represents the same program as the first one does. It shows, which mechanisms are automatically created during the compilation of C++ classes (simplified, of course).

Compilation of the C++ example:

cd oop_cpp
mkdir -p build && cd build
cmake ..
cmake --build .
# The result executable is oop_cpp

Compilation of the C example:

cd oop_c
mkdir -p build && cd build
cmake ..
cmake --build .
# The result executable is oop_c
