我按教程的输入了下面的程序：
（是个练习类组合的一个东东，在编译的时候，出现了问题，加上using namespace std;这句的话，说error C2871: 'std' : does not exist or is not a namespace，不加这句的话，说error C2676: binary '<<' : 'class istream_withassign' does not define this operator or a conversion to a type acceptable to the predefined operator，我英文也不好，看不懂是啥意思，是不是程序在玩我啊？
我想是我在什么地方弄错了的，哈哈，不过我真的找不到了，请高手帮我测试一下，然后把改后的程序再复制上来哟，谢过！
（这个问题已经解决）
另一个问题是：程序连接完后，.exe文件居然536KB，为什么会这么大呢？我感觉很奇怪的。。。
我认为要是在50K以内的话，才能算正常的吧，请高手指教。
