LIST - POP_FRONT() METHOD


pop_front() Method is used to remove an element from the beginning of a List.


Let us say, we have a List that contains three names, Mohan, Kriti and Salim. And we want to remove Mohan from the List.


It can be done with the pop_front() Method


Example :



#include <iostream>
#include <list>

using namespace std;

int main() {

    list<string> x = {"Mohan", "Kriti", "Salim"};
        
    x.pop_front();
    for (string data : x)  
    {  
        cout << data << endl;  
    }
    
    return 0;    
}


Output :



  Kriti
  Salim

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

Next, we have used the pop_front() method that searches for the first element(And the first element is Mohan) and removes it from the List.


x.pop_front();
java_Collections

Output :



  Kriti
  Salim
