C语言程序流程图绘制系统的设计与实现

The Design and Conduct of C Language Program Flowchart Drawing System

为使C语言学习者能把直观的流程图和抽象的程序结合起来,养成先绘制流程图再编写程序的良好习惯,开发和使用流程图绘制系统显得尤为重要。目前,流程图绘制软件多以直线、圆、三角形、四边形、多边形等几何图形作为基本图元,采用"图元+连接线"的绘制模式。为提高绘制流程图的效率,以程序基本结构为基本图元,使用"图元+装配"的绘制模式,设计了C语言程序流程图绘制软件,以使用户绘制流程图更直观、方便,且在图元编辑时不会引起流程图的变形,易学易用。

In order for the C language learner to combine the abstract programs and the visual flowchart, and cultivate the good habit of drawing a flowchart at first and then writing programs, it is very important to develop and use flowchart drawing system. Most of current flowchart drawing software takes the straight line, circle, polygon, triangle, and quadrilateral geometry as the graphics primitive, with drawing mode of ＂primitive ＋ connector＂. It takes the basic structure of C language system as the graphics primitive in this system, with the drawing mode of ＂primitive ＋ assemble＂, which can wake the flowchart more intuitive and more convenient, without chart deformation.
