std::string test("hello"); std::string::reverse_iterator rit = test.rbgin(); std::string::iterator it(rit.base());
首先看一下reverse函数的说明: template <class BidirectionalIterator> void reverse (BidirectionalIterator first, BidirectionalIterator last); 这个BidirectionalIterator和它的字面意思一样,就是iterators that can be used to access the sequence of elements in a range in both directions (towards the end and t...
&*(reverse_iterator(i) ) == &*(i– 1 ). In practice, this means that in the reversed sequence the reverse_iterator will refer to the element one position beyond (to the right of) the element that the iterator had referred to in the original sequence. So if an iterator addressed the...
19行的for loop,使用了reverse_iterator,讓我們很簡單的如操作一般的iterator般去處理reverse_iterator。 25行到29行,使用了一般的iterator去處理,程式有點詭異,主要是讓我們看出,若沒有reverse_iterator,程式有多難寫。 copy() algorithm也可搭配reverse_iterator,只需一行就可以了。

A type reverse_iterator cannot modify the value of an element and is use to iterate through the map in reverse.The reverse_iterator defined by map points to elements that are objects of value_type, that is of type pair*<const Key, Type>*, whose first member is the key to the element...
