The list::reverse() is a built-in function in C++ STL which is used to reverse a list container. It reverses the order of elements in the list container. Syntax:

list_name.reverse()

Parameters: This function does not accept any parameters. Return Value: This function does not return any value. It just reverses the order of elements in the list container with which it is used. Below program illustrate the list::reverse() function in C++ STL: 

CPP




// CPP program to illustrate the
// list::reverse() function
#include <bits/stdc++.h>
using namespace std;
 
int main()
{
    // Creating a list
    list<int> demoList;
 
    // Adding elements to the list
    demoList.push_back(10);
    demoList.push_back(20);
    demoList.push_back(30);
    demoList.push_back(40);
 
    // Initial list:
    cout << "Initial List: ";
    for (auto itr = demoList.begin(); itr != demoList.end(); itr++)
        cout << *itr << " ";
 
    // reversing the list
    demoList.reverse();
 
    // List after reversing the order of elements
    cout << "\n\nList after reversing: ";
    for (auto itr = demoList.begin(); itr != demoList.end(); itr++)
        cout << *itr << " ";
 
    return 0;
}

Output:

Initial List: 10 20 30 40 

List after reversing: 40 30 20 10

Time Complexity – Linear O(N)
