谢谢各位帮忙解决!!

这是C++Primer 259页的例子,照着打,出了好多错误,本人初学,谢谢各位大哥大姐告诉我错误原因,怎么改正,不甚感激!!
用的是VC++6.0

这些警告提示是么意思呀?

可能是头文件的事，C++的兼容性并不是我们想象的那样好，很多C++的编辑器都有它自己的类库，
这使得C++的可移植性大大降低。
我想C++ primer 不会出错吧，你换个编辑器试试！

我课程设计一道题目用到deque<string>

一个程序一个有52个类似的warning

但程序照样运行得很好^_^

不同意楼上的说法，warning的出现的确不影响编译，但是有些warning可是会导致语义错误（semantics error)的，所以最好确保编译程序时没有warning的出现。
