Question

In C++ code language please:

1. Created a linked list

2. Insert 5 values: 1, 10, 3, 20, 25

3. Point and print only even numbers in the list

Answer 1

//c++ program to print even numbers in created linkedlist

#include <iostream>

using namespace std;

struct Node {

int val; //variable to store data

struct Node *next; //pointer

};

struct Node* head = NULL; //initializing linkedlist head with NULL

void insert_node(int new_data) { //Function for inserting data into linked list

struct Node* new_node = (struct Node*) malloc(sizeof(struct Node));//allocating memory

new_node->val = new_data;

new_node->next = head; //inserting data

head = new_node;

}

void dis() { // Function for displaying data, in linked list

struct Node* ptr;

ptr = head;

while (ptr != NULL) {

if(ptr->val%2==0){ //checking even condition

cout<< ptr->val <<" ";//printing output

}

  
ptr = ptr->next; //changing position

}

}

int main() {

insert_node(1);

insert_node(10);

insert_node(3);

insert_node(20);

insert_node(25);

cout<<"The final linked list is: ";

dis();

return 0;

}

Output:-
