unordered_map end( ) function in C++ STL unordered_map::end()是 C++ STL 中的一个内置函数,它返回一个迭代器,该迭代器指向容器中最后一个元素之后的位置在 unordered_map 容器中。在 unordered_map 对象中,不能保证哪个特定元素被视为其第一个元素。但是容器中的所有元素都被覆盖,因为范围从开始到结束直到...
我们可以看到,通过迭代unordered_map容器中的元素,我们可以访问容器中的所有键和对应的值。在这个例子中,我们使用begin()函数获取了指向容器中第一个元素的迭代器,使用end()函数获取了指向容器中最后一个元素之后位置的迭代器,然后使用++运算符不断移动迭代器,访问所有的元素。
