Investigation of Value Trace Problem for C++ Programming Self-study of Novice Students

Presently, C++ programming has been taught in many universities around the world as first object-oriented language for undergraduate students to start studying concepts and computer architecture. However, of them may struggle due nature formal language. Thus, hands-on self-study tools can be effective. In previous, we have developed Java learning assistant system (JPLAS) assisting programming. JPLAS offers value trace problem (VTP) novice study through code reading study. a VTP instance, actual values important variable or standard output messages given source are questioned, where correctness each answer is checked string matching. this paper, investigate effectiveness by students. We generated 37 instances basic grammar using codes textbooks websites programming, asked 46 three countries solve interface JPLAS. The results suggest that most satisfactory, but some need cares at early stage.
