Types of Linked List

A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.

Linked List

When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).

How simple is it to transfer shared references into another array in C++? List approaches to tackle the issue. Do shared pointers transfer the objects they control? Explain?
The destination of a function's return value may be represented as a sequence of instructions. When making modifications to the stack, keep in mind that they must not prevent the method from returning to its caller.

What is a way to safely dereference a pointer?
1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.
