class="MsoNormal">Win32控制台程序界面类
我相信不少同学也和我一样，在刚学习c++的时候都会尝试做简单的图书管理系统，学生成绩管理系统等，做这些实验项目可以加深你对文件操作，vector，list等容器的熟悉度，还可以让你学会设计系统结构。
随着学习的逐渐深入，同学们也许会发现，很多时候我们只要调用标准库函数里的类，代码量就会少很多，如果我们在平时的练习里有意识地去封装一些也许会比较常用的类，那么是不是我们平时编程的效率也会快好多呢。
答案是肯定的，特别对于XXXX系统之类的程序来说，可供应的地方就更多了，要重复使用这些我们自己封装好的类，只要将我们做好的类的.h和.cpp文件与我们做好想做的程序的代码放在同一个文件夹里就好。
下面我就将我在做好的界面类与大家分享，由于时间仓促，所做的类的调用方法也比较少，
接下来的时间里，我会继续扩充该类的方法，以便适应未来工作学习的需要，同时也方便大家
头文件：windesign.h//划线类（专供windowDesigner.h使用）
??????? wndowDesigner.h//画界面类
其他要包含的cpp文件
questionwin.cpp
windesign.cpp
windowDesigner.cpp
?
?
windesign.h的方法：
???????? winDesign& leftSide(int,char);//首行缩进
???????? winDesign& leftSidec(int,char,char);//首行缩进做加左边框
???????? winDesign& Sidesc(int,char);//边框左
???????? winDesign& SidescR(int,int,char);//边框右
???????? winDesign& SidescL(int,int,char);//边框左2
???????? winDesign& centre(int,int,char,string);//中部内容
???????? winDesign& centre(int ,char );//中部标题,上下部边框
（绘制一行的内容需要用到其中的几个方法）
?
windowDesigner.h的方法：
?? ?? void mainwin(string sentence[],int n,int s);//画主界面//各行内容，选项数，缩进（选项数要大于sentence[]的元素数）
???????? void questionwin(string sentence[],int n,int s);//对话框//各行内容，选项数，缩进
?? void needinput(string sentence[],string input[],int n,int s);//需要输入的界面//
