2.const_iterator 对象可以用于const vector 或非 const vector,它自身的值可以改(可以指向其他元素),但不能改写其指向的元素值. 3.const iterator与const_iterator是不一样的:声明一个 const iterator时,必须初始化它。一旦被初始化后,就不能改变它的值,它一旦被初始化后,只能用它来 改它指的元素,不能使它...
看了一下返回值是std::vector::iterator 或是 std::vector::const_iterator , 在begin()后面加了一个点看到了iterator有下面还有一个iterator(果然是圆环套圆环)和加、减、[]等运算符操作,很是郁闷应该怎么转换呢?到vector里看了一下原来是一个类 class iterator 在里面看到了几个函数 const_reference operator...

The iterator debugging feature has been taught to properly unwrap std::move_iterator. For example, std::copy(std::move_iterator<std::vector<int>::iterator>, std::move_iterator<std::vector<int>::iterator>, int*) can now engage the memcpy fast path....
除了偵測 _ITERATOR_DEBUG_LEVEL 不符的情況 (實作於 Visual Studio 2010) 之外,Visual Studio 2012 的 C++ 編譯器還會偵測執行階段程式庫不符的錯誤。 當編譯器選項 /MT (靜態發行)、/MTd (靜態偵錯)、/MD (動態發行) 和 /MDd (動態偵錯) 混合時,就會發生這些不相符的情況。 針對std::unordered_map 和...
For example, suppose your code defines both a placement new and a placement delete: C++ Copy void * operator new(std::size_t, std::size_t); void operator delete(void*, std::size_t) noexcept; The problem occurs because of the match in function signatures between a placement delete op...
