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 performed and reverses the elements between the given range. ...
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...
co m vector<int> v(10); for(unsigned i=0; i < v.size(); ++i) v[i] = i*i; show("Contents of v: ", v); vector<int>::iterator itr; // Now, declare reverse iterator to a vector<int> vector<int>::reverse_iterator ritr; return 0; } void show(const char *msg, vector<...
示例:使用反向迭代器遍历 vector #include <iostream> #include <vector> int main() { std::vector<int> nums = {10, 20, 30, 40, 50}; std::vector<int>::reverse_iterator rit; for (rit = nums.rbegin(); rit != nums.rend(); ++rit) { std::cout << *rit << " "; // 输出每个元...
libc++的vector除掉注释，一共3100行左右。其中vector<bool>大概占1/3的代码，剩下的2/3是给平时用...

vector::iterator (STL/CLR) 受控序列的迭代器的类型。 vector::reference (STL/CLR) 元素的引用的类型。 vector::reverse_iterator (STL/CLR) 受控序列的反向迭代器的类型。 vector::size_type (STL/CLR) 两个元素间的带符号距离的类型。 vector::value_type (STL/CLR) 元素的类型。展开...
The reverse algorithm reverses the order of the elements in the range [First, Last). Example 複製 // reverse.cpp // compile with: /EHsc // Illustrates how to use the reverse function. // // Functions: // reverse - Reverse the items in a sequence. // disable warning C4786: symbol...
仿函数(Function object) 适配器(Adaptor) 空间配置器(allocator) 1、容器 作为STL的最主要组成部分--容器,分为向量(vector),双端队列(deque),表(list),队列(queue),堆栈(stack),集合(set),多重集合(multiset),映射(map),多重映射(multimap)。 STL容器能力表: ...
7 * erase uses a vector operation to remove the nonunique elements 8 */9vector<string>::iterator end_unique=unique(words.begin(),words.end());10words.erase(end_unique,words.end()); 在STL中unique函数是一个去重函数, unique的功能是去除相邻的重复元素(只保留一个),其实它并不真正把重复的元素...
