C Language Teaching Practice Based on Modular Design and File Operations

A Case Study of Classroom Roll Call System

Abstract

Aiming at the problems that students generally find grammar boring and theory divorced from practice in traditional C language teaching, this paper proposes to take the "classroom roll call system" as a comprehensive case, integrating two core knowledge points of modular design and file operations into teaching practice. By guiding students to decompose the system into independent modules such as menu, roll call, student management and file operations, and using files to achieve data persistence, the students' programming interest, system design ability and problem-solving ability are effectively improved. Teaching practice shows that this method improves the teaching effect and provides a reference path for the training of applied talents.
