Given a vector and we have to reverse their element using C++ STL program. Reverse a vector Toreverse vector elements, we can usereverse() functionwhich is defined in<algorithm>header in C++ standard template library. It accepts the range of the iterators in which reverse operation to be perf...

迭代器类vector::iterator 和 vector::reverse_iterator 的实现、迭代器类型、常用的容器成员 一、迭代器 迭代器是泛型指针 普通指针可以指向内存中的一个地址 迭代器可以指向容器中的一个位置 STL的每一个容器类模版中,都定义了一组对应的迭代器类。使用迭代器,算法函数可以访问容器中指定位置的元素,而无需关心...
