Abstract—In a lot of universities across the world, C programming is taught to novice students in the first programming course. To assist their self-studies, we have developed C programming learning assistant system (CPLAS) that offers various programming problems with different learning goals where any answer from a student is automatically marked at the system. In this paper, we studied the phrase fill-in-blank problem (PFP) in CPLAS for learning basic C programming. A PFP instance gives a source code where several key phrases (set of elements) are blanked and requests to fill in them by a student. The correctness of answers is checked through string matching with the original ones. For evaluations, we generated 22 PFP instances for learning basic grammar topics and logic functions and assigned them with previous 15 instances for recursive functions to 21 students in Okayama University. The results confirmed the correctness of the generated instances and found the weakness of students in C programming study.
