下面的代码编译时报告C2664错误: Error C2664: ´__thiscall std::list<int,class std::allocator<int> >::std::list<int,class std::allocator<int> >(unsigned int,const int &,const class std::allocator<int> &)´ : cannot convert parameter 1 from ´class std::istream_iterator<int,char,struct std::char_traits<char> > (__cdecl *)(void)´ to ´unsigned int´ This conversion requires a reinterpret_cast, a C-style cast or function-style cast 代码如下: istream_iterator<int> intFileEnd; list<int> intList(intFileBegin, intFileEnd); |
当VC6的库文件刚发布的时候,编译器还不支持Templated Member Function。这样,Templated List Constructor无法得到Non-List Iterators。 现在编译器虽然支持Templated Member Function,但要想编译通过,你还是需要一个新的标准库。前面的代码应该在以下环境中可以编译通过: n VC 7 n VC6 with Dinkumware library upgrade n VC6 with STLport 如果你没有这样的编译环境,那还是不要使用Templated Member Function。你可以这么做:
istream_iterator<int> intFileEnd; list<int> intList; copy(intFileBegin,intFileEnd,back_inserter(intList)); 这样同样可以把istream中的东西导入到list中。 |
