软件包中“圆弧连接已知圆和直线”问题的处理及C语言实现

Solving the Problems about “Arc Link the Known Circle and Knownline" in Geometry Intersection-tangency Software Package and Implement it in C Language

以“用圆弧连接已知圆和已知直线”这一问题为例，论述了在用Ｃ语言编制几何交切软件包时的有关问题的处理。

This article takes “arc links the known circle and known line” as an example. It discusses the solutions of the concerned problems when we compile geometry intersection-tangency software package in C language and present C language programm's flow diagram.
