- deque是一個動態陣列
- deque與vector非常類似
- deque可以在陣列開頭和末尾插入和刪除資料
#include <iostream> #include <deque> #include <algorithm> using namespace std; int main() { deque<int> a; a.push_back(3); a.push_back(4); a.push_back(5); a.push_front(2); a.push_front(1); a.push_front(0); for(size_t nCount = 0;nCount <a.size();++nCount) { cout <<"a[" <<nCount <<"] = " <<a[nCount] <<endl; } cout << endl; cout << endl; a.pop_front(); a.pop_back(); /* for(size_t nCount = 0;nCount <a.size();++nCount) { cout <<"a[" <<nCount <<"] = " <<a[nCount] <<endl; }*/ deque<int>::iterator iElementLocater; for(iElementLocater = a.begin();iElementLocater !=a.end();++iElementLocater) { size_t nOffset = distance(a.begin(),iElementLocater); cout << "a[" << nOffset << "] ="<<*iElementLocater <<endl; } cout << endl; cout << "Hello world!" << endl; return 0; }
結果輸出:
a[0] = 0 a[1] = 1 a[2] = 2 a[3] = 3 a[4] = 4 a[5] = 5
a[0] =1 a[1] =2 a[2] =3 a[3] =4
