data and operations that the parent base class defines. In practice, inheritance is used in two major ways in C++: implementation inheritance, in which actual code is inherited by the child, and interface Magic There are various tricks and utilities that we use to make C++ code more robust, and various ways we use C++ that may differ from what you see elsewhere. Ownership and Smart Pointers Prefer to have objects, such as the polymorphic wrapper std::function. • Lambdas are much more concise than other ways of defining function objects to be passed to STL algorithms, which can be a readability im- provement

Repeatable experiments simplify your own work  There is no single way how to do it right  There are many ways how to do it wrong  Basic Planning  Which data / data sets should be used?  Which workload /

deterministic formula showing exactly how to line- wrap in every situation. Very often there are several valid ways to line-wrap the same piece of code. Note: While the typical reason for line-wrapping is to avoid

Recommendations  Avoid sections with only one subsection (e.g., 2 and 2.1)  Avoid more than two or at most three nesting levels  Clearly separate motivation/background from your own work Scientific Writing 17
