How to Convert a Vector to a List Without Losing Element Order in C++?

In C++, vectors are dynamic arrays that store data in contiguous memory locations whereas lists are sequence containers that store data in non-contiguous memory locations. In this article, we will learn how to convert a vector to a list without losing the order of elements in C++.

Example:

Input:
myVector = {1, 2, 3, 4, 5};
Output:
myList = {1, 2, 3, 4, 5};

Converting a std::vector to a std::list in C++

To convert a std::vector to a std::list while preserving the order of the vector elements in the list, we can use the list constructor provided by the STL that takes the std::vector::begin() and std::vector::end() iterators and generates a list by preserving the order of the elements.

C++ Program to Convert a Vector to a List Without Losing Element Order

The following program illustrates how we can convert a vector to a list without losing the order of the elements of the vector.

C++

// C++ Program to illustrate how to convert a vector to a
// list without losing the order of the elements
#include <iostream>
#include <list>
#include <vector>
using namespace std;

int main()
{
    // Initialize a vector
    vector<int> myVector = { 1, 2, 3, 4, 5 };

    // Convert the vector to a list
    list<int> myList(myVector.begin(), myVector.end());

    // Print the list
    for (auto& element : myList) {
        cout << element << ", ";
    }
    cout << endl;

    return 0;
}

Output

1, 2, 3, 4, 5, 

Time Complexity: O(N), where N is the size of the vector.
Auxiliary Space: O(N)
