1. Start with analysing the problem by using a flowchart/pseudo code. 2. As mention above, build a C++ program based on the appropriate method/function. You are free to create your own menu and display. Consider the following case: You have been appointed as a teacher of 3 Gemilang class in SMK Tanjung Malim. Please create a program that can keep the name list of your students in the class. The list must consist of two lists, first list is for all female student's names and the second list is for all male student's names. You must also provide the list of all the student's name. In order to do that, you need to merge both of the list together. The name in the list needs to be sorted alphabetically. The program must consist of the following method function: a) menu() – as interface for the user b) add list(string) – to add name to the list c) sort list() – to sort the name in the list d) show list) – to display the lists e) search list(string) – to search a name in the list ) merge…

It is a to the next node in the linked list, which is the property after it in the Node class.
struct node{ int a; struct node * nextptr; }; Write two functions. One for inserting new values to a link list that uses the given node structure. void insert(struct node **head, int value); Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers. int countEvenNumbers(struct node *head); Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen. Note 1: Do not modify the function prototypes.

card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
Multiple choice in data structures void doo(node<int>*root){ if(root !=0) { node<int>*p=root; while(root->next!=0) root=root->next; p->data=root->data; } What is this code do? a. swap the first item with the last item in the linked list b. set the first item in the linked list as the last item c. doesn't do anything because the root parameter is passed by value d. change the root item in the binary tree with the farthest leaf item
