小小请教一下：vector的引用如何遍历（和类型转换）？

用智能指针吧（std::tr1::shared_ptr）

die

没有必要，去知道iterator的类型。

#include<vector> #include<string> #include<iostream> using namespace std; template< typename T> inline void print( T begin, T end){ &nbsp;&nbsp;&nbsp;&nbsp;while( begin != end) &nbsp;&nbsp;&nbsp;&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cout<<*begin++<<endl; &nbsp;&nbsp;&nbsp;&nbsp;} } template< typename T> inline void print_all( const T& container ){ &nbsp;&nbsp;&nbsp;print( container.begin(), container.end()); } int main(){ &nbsp;&nbsp;&nbsp;vector<string> values; &nbsp;&nbsp;&nbsp;values.push_back( "this"); &nbsp;&nbsp;&nbsp;values.push_back( "is"); &nbsp;&nbsp;&nbsp;values.push_back( "only"); &nbsp;&nbsp;&nbsp;values.push_back( "a"); &nbsp;&nbsp;&nbsp;values.push_back( "test"); &nbsp;&nbsp;&nbsp;print_all( values); &nbsp;&nbsp;&nbsp;return 0; }
