摘  要



本系統(tǒng)采用目前普遍的C / S結構，主要形式是學生和管理員操作各種數(shù)據(jù)庫，服務器端的客戶端的運行結果送回顯示在客戶端的數(shù)據(jù)庫服務器，使得人機交互更方便，更快捷。本學習系統(tǒng)的主要任務是把各種題目按C語言知識點一一分類,然后分別按各個知識點和題型入庫,最后通過可視化編程語言設計界面,并與數(shù)據(jù)庫進行連接,從而達到使用戶學習C語言、掌握知識點的最終目的。本系統(tǒng)采用現(xiàn)在較為流行的C/S模式,即客戶端/服務器模式。用戶的數(shù)據(jù)庫由服務器進行管理,利用可視化編程工具進行界面設計,操作結果又由服務器的數(shù)據(jù)庫將數(shù)據(jù)在客戶端顯示,從而完成對數(shù)據(jù)的入庫、出庫、修改等操作?；谏蠙C學習支撐平臺就是以C語言知識為基礎，以學生上機自主學習為中心，為學生提供學習服務的一個平臺系統(tǒng)。

ABSTRACT







At present, the system uses common C / S structure, mainly in the form of students and administrators to operate a variety of databases, server-side client of the results shows that the client back to the database server, making human-computer interaction more convenient and more efficient. The main task of learning system is subject to a variety of points according to C-11 classification of knowledge, and knowledge, respectively, according to various storage points and questions, and finally through the design of visual programming language interface, and connect with the database, thus to achieve learning C language allows the user to grasp the ultimate goal of knowledge points. The system is now more popular C / S mode, that is, client / server model. Users from the database server management, the use of visual programming tools, interface design, operation results from the database server will be displayed on the client data in order to complete the data storage, a library, modify such operation. Computer-based learning platform is to support knowledge-based computer, the machine independent student learning centers, learning services to provide students with a platform for the system.
