【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：

 1 #include <deque>
 2 #include <iostream>
 3 using namespace std;
 4 int main()
 5 {
 6     deque<float> fdeque; 
 7 
 8     for(float f = 1.1; f < 9.9; f += 1.1){
 9         fdeque.push_front(f);
10         fdeque.push_back(f);
11     }
12         
13     for(int i = 0; i <= (fdeque.size() - 1); i++)
14         cout << fdeque[i] << " | ";
15 
16     return 0;
17 }
