C++ List reverse()

C++ List reverse() function reverses the order of the elements in the list container.

Syntax

Parameter

It does not contain any parameter.

Return value

It does not return any value.

Example 1

Let's see a simple example when the list contains integer value.

#include <iostream>
#include<list>
using namespace std;
int main()
{
   std::list<int> li={1,2,3,4,5,6};
    cout<<"content of list li is :";
    for(list<int> :: iterator itr=li.begin();itr!=li.end();++itr)
    cout<<*itr;
    li.reverse();
    cout<<'\n';
    cout<<"After reversing, content of list li is :";
    for(list<int> :: iterator itr=li.begin();itr!=li.end();++itr)
    cout<<*itr;

    cout<<'\n';
    return 0;
}

Output:

content of list li is : 123456
After reversing, content of list li is : 654321

In this example, reverse() function reverses the content of the list li and the output is 654321.

Example 2

Let's see a simple example when the list contains string.w

#include <iostream>
#include<list>
using namespace std;
int main()
{
   std::list<string> li={"mango", "is", "a", "fruit"};
    cout<<"content of list li is :";
    for(list<string> :: iterator itr=li.begin();itr!=li.end();++itr)
    cout<<*itr<<" ";
    li.reverse();
    cout<<'\n';
    cout<<"After reversing, content of list li is :";
    for(list<string> :: iterator itr=li.begin();itr!=li.end();++itr)
    cout<<*itr<<" ";

    cout<<'\n';
     return 0;
}

Output:

content of list li is : mango is a fruit
After reversing, content of list li is : fruit a is mango

In this example, reverse() function reverses the list of the string and the output is "fruit a is mango".
