Introduction
We give an introduction to advanced topics of C++. These include inheritance, templates, stable numerical calculations, debugging and profiling. The main focus is on rules and guidelines to write clear code and avoid common pitfalls.

Exercises
Monte Carlo method for moment of inertia
Random numbers can be used to solve complex integrals. Here, you are asked to compute the moment of inertia 
of a thin cylindrical shell and a cylinder, with radius R and length l. View the body as a composition of points with equal mass and sum up each point's moment of inertia 
.
Start with the program: File:Cylinder.cc
To get started, execute:
mkdir inertia cd inertia wget https://wiki.scc.kit.edu/gridkaschool/index.php/File:Cylinder.cc mv Cylinder.cc cylinder.cc g++ -o cylinder cylinder.cc ./cylinder
Version Control
Create the root directory of CVS:
mkdir cvsroot cvs -d $PWD/cvsroot init
Point CVSROOT to the new directory:
export CVSROOT=<full path to cvsroot>
Import your project into CVS:
cd inertia cvs import -m "start" Inertia INITIAL start
Test it:
cd cvs co -d inertiawork Inertia
Other commands:
cvs diff cvs status cvs commit -m"precise description" <files> cvs diff --brief cvs up
Implement a 3D-Vector
In order to make our program more general (different bodies, different axis) we need a class for 3D vectors that can also compute the cross product.
- Complete the class implementation with the following files: File:Vector.hh,File:Vector.cc,File:Vektortest.cc
- Adapt cylinder.cc to use the new Vector class
