C++：vector容器练习 输入单个字符 感觉实际上比较通用

解题思路:

注意事项:

参考代码:

#include<bits/stdc++.h>

using namespace std ;

int main ( )

{

         char ch ;

         int record = 0 ;

         vector<int> v ;

         while ( cin.get(ch) && ch!='\n' )

         {

                 record ++ ;

                 v.push_back(ch-'0') ;

         }

         cout << record << endl ;

         for ( int i : v ) cout << i << " " ;

         cout << endl ;

         for ( auto i = v.rbegin() ; i != v.rend() ; i++ )

         {

                  cout << *i ;

         }

         return 0 ;

}
