很简单的一个问题

#include   <vector>  
  #include   <iostream>  
   
  int   main()  
  {  
   
              vector<int>   ivec   ;  
              cout<<"ivec:size:"<<ivec.size()  
              <<"capacity:"<<ivec.capacity)_<<endl;  
   
              for     (int   ix=0;ix<24,++ix){  
              ivec.push_back(ix);  
              cout<<"ivec:size:"<<ivec.size()  
              <<"capacity:"<<ivec.capacity)_<<endl;  
              }  
   
  }  
   
  很简单的一个程序  
   
   
  用dev4编译，通不过  
  c++库路径设置正确，在其中找到了vector和iostream  
  但是编译时提示：

  请问是怎么搞的啊？  
  还有为什么是vector和iostream，而不是vector.h和iostream.h呢？ 问题点数：20、回复次数：4Top

using   namespace   std;    
  在   #include   <iostream>   下面   加上这个再编译Top

这个我加了，还是一样的错误结果，到底是怎么搞的啊Top

???  
   
  #include   <vector>  
  #include   <iostream>  
   
  using   namespace   std;  
   
  int   main()  
  {  
   
              vector<int>   ivec   ;  
              cout<<"ivec:size:"<<ivec.size()  
              <<"capacity:"<<ivec.capacity()<<endl;  
   
              for     (int   ix=0;ix<24;++ix){  
              ivec.push_back(ix);  
              cout<<"ivec:size:"<<ivec.size()  
              <<"capacity:"<<ivec.capacity()<<endl;  
              }  
   
      return   0;  
   
  }  
   
  这个可以编译通过的(在vc6.0)下...Top

天啊，全是拼写错误，我要疯了，谢了！！！Top
