The enum class construct: Select one: a. does not require one to write anything in front of an enumeration value-name b. requires one to use the name of the enumeration, followed by "::" (colon-colon), before each name whenever the enumeration's value-name is used c. requires one to use the name of the enumeration, followed by "." (period), before each name whenever an enumeration's value-name is used
C# Encapsulation Example Following is the example of defining an encapsulated class in c# programming language. using System; using System.Text; namespace Tutlane { class User { private string location; private string name; public string Location { get { return location; } set { location = value; } } public string Name { get { return name; } set { name = value; } } } class Program { static void Main(string[] args) { User u = new User(); // set accessor will invoke u.Name = "Suresh Dasari"; // set accessor will invoke u.Location = "Hyderabad"; // get accessor will invoke Console.WriteLine("Name: " + u.Name); // get accessor will invoke Console.WriteLine("Location: " + u.Location); Console.WriteLine("\nPress Enter Key to Exit.."); Console.ReadLine(); } } } As you can see from the example above, we used properties to specify the fields in the enclosed class, and we can change the values of the fields by using the get and set accessors of properties. 1.

TIME CLASS (Language: C++) - Write a time class named timeClass - Write code to demonstrate that it works - The timeclass class will be named timeClass - The class must have these 3 constructors: #1) timeClass(); #2) timeClass(int h, int m, int s); #3) timeClass (string timeIn); - The string constructor must be capable of being separated by colons or blanks time in the 24-hour format: example 23:11:07 or 9:4:9 or 11 31 27 - DO NOT use some system functions for this assignment. You must write the code. - Yes, you can convert from string to integer stoi ( string). - In addition to the constructors, you should supply a set of getters (Accessors) getH, getM getS - In addition to that, add mutators that allow the individual setting of Hours, Minutes and Seconds: setH(int), setM ( int ) setS( int ) Include this setter ( Mutator) setTime( int NumSeconds); - So if I call setTime( 7673) you would know that that is: -- hours, -- minutes and -- seconds seconds = 53 7673…
Rolling Dice Simulator [Java Assignment]Objective: Create a Java program that rolls two dice and displays the results. The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…

Java Program 01 - Theater Ticket System A small ten-seat theater has contracted you to build software which will reserve tickets. The theater has two rows of five seats each. Each row is referred to by number (1 or 2) and each seat in the row is referred to by letter (A, B, C, D, and E). When started, the program should ask the user for the row they prefer (row selection). If that row has no empty seats then the program should ask the user if they prefer the other row, if no then display a message stating the next show is tomorrow. Upon selecting a row, the program should present the user with a choice of available seats in the row. The user can then either choose a seat and print the ticket (in this case a simple message will suffice) or return to row selection. If a ticket is printed the program should return to row selection. The program terminates when all seats are reserved. Please enter a row: 1 Available seats: A B C D E Which seat, enter Q for none?: B You have…

Usernames An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below: Username MUST contain at least 6 characters; Username cannot start with a number; Username can only contain letters or numbers. If valid, the username may be resgistered if it doesn't already exist in the system. You should not use built-in functions to determine the character type such as isnumeric() or islower(). Use the strings given alphabet and numeric to determine if each character is valid. Use the list registered to help you determine if the username is already registered. Don't forget to execute the cell below to use these strings # run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"] Write a function nameValidation which receives a String argument name.
