Facilitating problem-solving on nested selection statements using C/C++

Problem solving is an important part of learning computer science, yet the choice of problems offered in textbooks (which is the traditional source of problems) is limited, static, non-interactive and lacks animation. In order to address these issues, we propose Java applets that automatically generate problems, provide the necessary visualization and animation, solve problems and provide feedback to the user. They are also capable of logging usage. We refer to such applets as “problets”. In this paper, we discuss the issues involved in the design and implementation of a problet on nested selection statements in C/C++
