IFD:EAI SoS21/introduction to c++

1. Basics

You can find (and edit) the code examples from today in the following links:

   Data Types
   Classes
   Pointers

As your homework task I want you to extend the code in Repl.it. as follows:

1. For the "Classes" example above, add a Header (Point2D.h) and a Function definitions (Point2D.cpp) file to the project where you define the class and its functions seperately. Finally include the header file with #include "Point2D.h" in the main.cpp file, so we can use our custom C++ class. Watch the online tutorial below to learn how to do that!

You don't need to put the .h and .cpp file in different folders, as shown in the video. Putting them in the same folder as the main.cpp works as well.

1. As a second task, I want you to extend the code of the Point2D to include a function to measure the distance between two points in 2D space. Do you remember the "Theorem of Pythagoras"?

   the function body should look like this:

   float distanceToOtherPoint(Point2D otherPoint) {
      float distance = ... // calculate distance here
      return distance;
   }

   include that function in our Point2D class and make it calculate the distance!
