C++ - REVERSE A LIST


How to reverse a List?


Reversal of a List can be done using reverse() method. It is independent of the alphabets. And is not a sort. It is just a reversal.


Example :



#include <iostream>
#include <list>

using namespace std;

int main() {

    list<string> x = {"Mohan", "Kriti", "Salim"};
    x.reverse();

    for (string data : x) {  
        cout << data << endl;  
    }
    
    return 0;    
}


Output :



  Salim
  Kriti
  Mohan

So, in the above code we have created a List and initialised to the variable x.


list<string> x = {"Mohan", "Kriti", "Salim"};

Below is how the values are positioned in the List,

java_Collections

Then we have used the reverse() Method to reverse the elements of the List x.


x.reverse();

And the List x gets sorted in reverse order with Salim as the first value, Mohan second and Kriti as the third.

java_Collections

And we get the below output.

Output :



  Salim
  Kriti
  Mohan
