【STL】-deque的用法

初始化：

#include <deque>

deque<float> fdeque;

算法：

fdeque.push_front(f);

fdeque.push_back(f);

fdeque.size()

代码：

#include <deque>
#include <iostream>
using namespace std;
int main()
{
    deque<float> fdeque; 

    for(float f = 1.1; f < 9.9; f += 1.1){
        fdeque.push_front(f);
        fdeque.push_back(f);
    }
        
    for(int i = 0; i <= (fdeque.size() - 1); i++)
        cout << fdeque[i] << " | ";

    return 0;
}

输出：
