------解决方案--------------------
经测试，没错误，我的编译器是netbeans
------解决方案--------------------
？什么意思？链接的时候出错了么？不过LZ啊，你要是这么继承类的话，那基类的两个方法最好用虚函数....
把具体错误信息发上来吧...这样看没意义
------解决方案--------------------
DEV-CPP下没问题
------解决方案--------------------
应该是没错的
------解决方案--------------------
单个文件是没有办法看出link时的问题的……

该文件在vs2008下能够build成功
------解决方案--------------------
继承的类怎么又写了一遍set和put，直接用父类的不就行了吗～
------解决方案--------------------
去掉万恶的“预编译头文件”选项，重建所有！
