Question

WAP to implement the Linear linked list. Perform the following operations on the linked
list:
 Creating an empty linked list
 Adding the numbers at the beginning of the linked list.
 Addition of numbers after a particular location.
 Counting the no of nodes.
 Displaying the linked list.

Answer 1

#include <iostream>
#include <list>
#include <iterator>


using namespace std;


class MyList : public list<int>
{
public:
    void showlist()
    {
        list <int> ::iterator it;
        for (it = this->begin(); it != this->end(); ++it)
            cout << *it << " ";
        cout << '\n';
    }
    int countlist()
    {
        int count = 0;
        list <int> ::iterator it;
        for (it = this->begin(); it != this->end(); ++it)
            count++;
        return count;
    }


private:
};


int main()
{
	MyList test;        // creating empty list
    // Adding the numbers at the beginning of the linked list
    cout << "Insert 3 values: " << endl;
    test.push_front(2);
    test.push_front(5);
    test.push_front(1);
    cout << "Display values in list: ";
    test.showlist();    // Displaying the linked list
    cout << "Number nodes in linked list: " << test.countlist() << endl;


    system("pause");
	return 0;
