C++deque容器deque 数据存取

C++deque容器deque 数据存取

功能描述：

对deque 中的数据的存取操作 #include <iostream> #include <deque> using namespace std; void printDeque(const deque<int>& d) { for (deque<int>::const_iterator it = d.begin(); it != d.end(); ++it) { cout << *it << " "; } cout << endl; } void test() { deque<int> d; d.push_back(10); d.push_back(20); d.push_back(100); d.push_back(200); for (int i = 0; i < d.size(); ++i) { cout << d[i] << " "; } cout << endl; cout << "front: " << d.front() << endl; cout << "back: " << d.back() << endl; } int main() { test(); return 0; } //除了用迭代器获取deque容器中元素，[]和at也可以 //front返回容器第一个元素 //back返回最后一个元素
