STL中vector容器实现反转(reverse) vector容器中实现可以通过以下两种方式实现: #include"stdafx.h"#include<vector>#include<iostream>//#include <math.h>#include<algorithm>usingnamespacestd;int_tmain(intargc, _TCHAR*argv[]) { vector<int>arrayInt; arrayInt.resize(10);for(inti=0;i<10;i++) { a...
int a[] = {1, 2, 3, 4, 5}; vector<int> v1(a, a + 5); cout<< "原始数据向量v1 : "; copy(v1.begin(), v1.end(),ostream_iterator<int>(cout, " ")); cout<< endl; cout<< "反转向量 v1(reverse): "; reverse(v1.begin(), v1.end()); copy(v1.begin(), v1.end(...
简言之，如果有M种容器、N种通用算法，你的做法要写M*N份实现，而STL的做法只需要M+N份实现。

Reversing a vector in C++ means changing the order of its elements so that the last element becomes the first, the second-to-last becomes the second, and so on. Essentially, the vector is flipped in the opposite direction.For example, if the Initial Vector is {1, 2, 3, 4, 5} then...
