C++ List front

The front method in C++ List retrieves the initial element of the list, offering direct access to that specific element.

Difference between front and begin

The begin function provides an iterator pointing to the element, whereas the front function gives a direct reference to that particular element.

Syntax

reference front();

Parameter

It does not contain any parameter.

Return value

It provides the explicit pointer to the initial element.

Example 1

Let's examine a basic scenario where the list consists of integer values.

#include <iostream>
#include<list>
using namespace std;
int main()
{
    std::list<int> li={1,2,3,4,5};
    std::cout <<"front() is :"<< li.front() << std::endl;
    return 0;
}

Output:

front() is : 1

In this instance, the front method retrieves the initial element from the list, which is 1.

Example 2

Let's examine a basic illustration involving a list that holds character values.

#include <iostream>
#include<list>
using namespace std;
int main()
{
    std::list<char> li={'j','a','v','a'};
    std::cout <<"front() is :"<< li.front() << std::endl;
    return 0;
}

Output:

front() is : j
