linux下练习 c++ 容器的deque的特性

/*deque特性下标：.operator[](i)不检查越界，.at(i) 删除：.pop_front()，.pop_back()*/#include<iostream>using namespace std;#include<deque>#include "print.h"int main(){deque<char> dq;dq.push_back('c');dq.push_back('d');dq.push_back('e');dq.push_back('f');print(dq.begin(),dq.end());dq[1]='t';//把 d 改为 tfor(int i=0;i<dq.size();i++)cout<<dq[i]<<' ';cout<<endl;dq.pop_back();//删除最后一个dq.pop_front();//删除第一个print(dq.begin(),dq.end());return 0;}

 

//print.h
