Push and print elements in an integer deque in C++ STL

C++ STL deque: Here, we are implementing a program in which we are declaring an integer deque, pushing the elements and printing the elements.

In this example, we are declaring an integer deque and pushing the elements using a for loop with the counter starting value from 1 to 5 and then printing the value separated by space.

Code:

#include <iostream>
#include <deque> //for deque
using namespace std;

int main()
{
    // deque  for integer elements
    deque<int> d1;

    // adding 5 elements
    for (int i = 1; i <= 5; ++i) {
        d1.push_back(i);
    }

    // print all elements
    cout << "deque elements are: ";
    for (int i = 0; i < d1.size(); ++i) {
        cout << d1[i] << ' ';
    }
    cout << endl;

    return 0;
}

Output

deque elements are: 1 2 3 4 5
