a Description In this assignment, you are going to build a subprogram that maintain a unoredered list of user accounts. Each node of the list will store the information of one user account. You need to implement the following classes User AccountType. User AccountNode and User AccountListType. Their specifications are shown in the UMLs (Figures 1, 2 and 3). User AccountType is the class that define the attributes of a user account including the user ID, the user password, First Name, Last Name. It is very important to implement a default constructor beside the parametrized constructor of User AccountType.otherwise you will get a syntax error when you implement the class User AccountNode that has a composition of the class User AccountType. (Alternatively, we can create parameterized contractor of User.centNode that passes the argument to the parameter constructoe of User AccountNode. but you don't have to implement that way User AccountNode is the type that you will see to create nodes and them to a list (object) of the class User AccountListType. Each node you will create has two member elements: 1) an object of the type User AccountType. 2) a link (pointer of the type User AccountNode) that points to the next node in the list. User AccountListType is used to create an unordered list of user accounts. The list a collection of nodes of the type User AccountNode. Each user account in the list has user id, these user ids should be unique. Which means that it is not acceptable to have two nodes in the list with the same user id. In other words, the user id is a key. Figure 4 is a sample user accounts list of type in User AccountListType. class User Account Type 33 pes) #userld: string wer ID.e. ahmadali #encrypted password: string # FirtsName : string #LastName : string User AccountType) mi po default construct that all of the member alles. 10 *** +User Account Type (string, string, string, string) 30 Set the values of the parameters to the member variable, you need to make sure that the passwoed is a valid passw, therwise it to if it is a valid password, it should be encrypted first and then being set to the member variable encrypted posword setuserId(string): void setFirstName(string): void setLastName(string): void setPassword(string): void you need to make sure that the password is a valid password, otherwise set it to if it is a valid passwont, it should be encrypted first and then being it to the member variable enesytet password getUserId():string) return the world isCompleteuserAccount():bool Ipt) return true if cache member values are set to some value other than if it least one of them is the return false encryptPassword (string): (12 pt this function evenes the original pacewond and return it atter encryption The encryption procedure is described below printUser Info():void wat print the values of all member vabies isvalidPassword(string pw): boole return true if the passed a valid or falso otherwise.

A sample user account list Password Encryption You are NOT allowed to use string operations Or array declaration in the encryption process. You are asked to declare lists stacks and Queues of type char from the STL to encrypt the password to get full score. Encryption Algorithm Step 1: (2 points) In this step the password characters will be inserted into list object to be ready for the coming encryption stages. (objects to use only list) Step 2: (2 points) In this step, the first and last characters of the password (within the list) will be reversed. (eg H21*10 0711H) (objects to use only list) Step 3: (5 Points) In this step, the ASCII value of the characters will be changed and the new characters (after changing the ASCII) will be in original order in the list. The new ASCII value for each character will be calculated by adding to the current ASCII value the least significant digit from the ASCII of the next character. (e.g. After step 2, the password is: Dell with ASCII values: 0: 111 7:55, 1: 108 *:42 1: 108. H: 72 The new ASCII values will be t: 111.5, ?: 55, 1012 2:48 n: 10+2, H: 72 The password will be: t?nnel Note: The ASCII for the last character will not be changed because there is no character next to the last one. (objects to use list and stack or list and queue or both) give explanation for your choice. Step 4: (4 points) Finally, in this step, the characters in even positions will be reversed and you keep the characters in the odd positions in their original order. (e.g. After step 3, the password is : thanh so after applying step 4 the password will be : ninath (objects to use list and stack Ok list and queue or both) glve explanation for your choice. Important notes: No templates are used. Add the time complexity of each function as a comment before the function header Implement the functions outside the classes Implement the classes and their functions as specified in the UML. (by the green comment). You must write a driver program (main function) to test the functions you implemented. You are responsible for designing test code (main function) that helps us to see if your functions are implemented properly. In the test code, you define an object of the class User AccountListType and call the functions. You need to place your test code inside a file called main.cpp. During grading, we are also going to use our own test code to check if your code is written properly or not. A sample test run is presented in figure 5. Think of the following seenarios when you test your code
