摘要
程序设计是一个循序渐进的过程，只有不断地针对问题， 解决问题才能逐步提高程序的质量。本文就环形链问题， 对衡量程序质量的首要条件──具有良好的结构， 容易阅读和理解做一些探讨。
Programming is a step process． In order to improve the puality of programming，we must aim at the problems appearing in the programming and solve them．This paper discusses the method of structural programming by analyzing the of ringline chain．
