This book is intended as course material for the course Structured Programming with C/C++ at university level. It contains eight chapters, one for each lecture of the course. The chapters are:
1. Introduction to programming. Here we go through general principles about what programming means. You will be introduced to the development tool Microsoft Visual C++ and build your first programs.
2. Variables. Here we start from the beginning and explain all details in the first programs. You will learn what variables are and how they are used for storing of values needed in the program....
This article summarizes expertise gleaned from the first years of Internet-based experimental research and
presents recommendations on: (1) ideal circumstances for conducting a study on the Internet; (2) what precautions have to
be undertaken in Web experimental design; (3) which techniques have proven useful in Web experimenting; (4) which
frequent errors and misconceptions need to be avoided; and (5) what should be reported. Procedures and solutions for
typical challenges in Web experimenting are discussed.
