系统工程课本中框图实现

特点是

1、　　运用动态存储，节省空间。

2、　　算法严格按照框图，便于理解

3、　　输入输出较简洁，而且满足要求。

这三个程序的主要缺点是：

1、　　输入输出界面不够友好，用DOS界面交互，不如图形界面好

2、　　输入必须以固定格式，没有安全性检验，一旦输错必须重新输入；

3、　　在“矩阵划分”的程序中，输入不够灵活，同时由于动态分配内存，矩阵元素定位时间长，时间复杂度增加。

-Systems engineering textbooks realize diagram is characterized by one, the use of dynamic storage, save space. 2, algorithm in strict accordance with the diagram for easy understanding of 3, the input and output more concise, but also meet the requirements. The three major shortcomings are as follows: 1, input-output interface not friendly, interactive interface with DOS, it is better to a good graphical interface 2, input must be fixed format, there is no safety inspection, once the need to re-enter mismatched　3, in the
