自己设计的一个简易的考勤管理系统，所使用的数据库为acce

采用C++语言编写，用来完成数据结构中中缀变后缀的程，以及利用中缀式计算四则运算表达式的程序

1.通过鼠标拖拽和弹出对话框完成实体、属性、联系的绘制以及各参数设定 2.对绘制的实体、属性、联系提供合法性检查 3.对绘制的图形进行拖动、重设大小、删除 4.通过属性对话框对实体、属性、联系的各种参数进行重新设置 5.数据的串行化 6.将绘制完成的E-R图转换成数据库脚本-1. Through mouse drag and drop and pop-up dialog box to complete entities, attributes, links, as well as drawing parameter setting 2. Drawing entities, attributes, links provided to check the legality of 3. The graphics on the drawing drag, reset size, delete 4. through the Properties dialog box on the entities, attributes, linked to various parameters re-set 5. serialization of data 6. will be drawn to complete the ER diagram into a database script

求图的任两结点间的距离，(2) 用二维数组存放C和A ，C是原成本矩阵，A 是求出的距离矩阵 (3) 算法采用三重循环，其中最外层的循环变量必须代表中间结点，中层的循环变量代表头结点而内层循环变量代表尾结点。 (4) 试着把三层循环变量的顺序作些改变，最外层的循环变量仍代表中间结点，而中层循环变量代表尾结点，内层循环变量代表头结点。把两种做法所得结果作比较,看结果是否相同 (5) 显示结果要清晰易懂 (6) 本题运行结果 -Order to map any of the distance between two nodes, (2) with two-dimensional array of storage C, A, C is the original cost matrix, A is to find the distance matrix (3) The algorithm uses the triple loop, one of the most outer loop variable must be representative of intermediate nodes, the middle loop variable represents the first node and the inner loop variable represents the end nodes. (4) tried to three-loop order of the variables to make some changes, the most outer loop variables still represent intermediate nodes, while the middle loop variable represents the end nodes, the inner loop variable represents the first node. The two approaches to compare the results to see whether the results the same (5) shows the results must be clear and understandable (6) The q
