Does the assignment implement new_line, three_lines, nine_lines, and clear_screen functions, as well as a main section of the program which calls the functions? Does the assignment demonstrate the use of nested function calls? Does the assignment produce the appropriate output when executed? The output should be recorded in a text file, a…
Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).

Language is c++ Assignment 6 C: Minesweeper - Simplified. For many years, computers sold with the Windows operating system would contain a game called M inesweeper. The player would be presented with a grid, where they would have to click an empty part of the map. If they clicked on a hidden mine, the game would be instantly over. However, if they clicked a safe spot, a hint about nearby mines would be displayed and the player would click another spot. The goal would be to flag all the hidden mines without hitting one. (As an aside, many people did not know these rules and just clicked around randomly until they hit a mine)We will be developing a simplified version of this game. You will prompt the user for a grid size and then created a 2D array with equal width and height (C++ students: Check the Appendix for more information on how to do this). You will initialize the 2D char array with each element equallying a ‘?’ symbol. You will then randomly generate one “mine” value per…
Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

Scylla or Charybdis? def scylla_or_charybdis(moves, n): This problem was inspired by the article "A Magical Answer to the 80-Year-Old Puzzle" in Quanta Magazine. Thanks to your recent cunning stunts, your nemesis in life is trapped inside a devious game where, for a refreshing change from the usual way of things, you get to be the Final Boss. (Everyone is the hero in their own story until they become a villain in somebody else's, after all.) This final level is a one-dimensional video game platform that reaches n-1 steps from its center to both directions. At each end of this platform exactly n steps away from the center, your two lethal friends Scylla and Charybdis are licking their lips in anticipation of a tasty morsel. Your nemesis starts at the center of this platform. To start this deadly combat of wits, she must immediately commit to her entire sequence of future moves, given to this function as a string of characters '+' (“� just a step to the ri-i-i-i-ight � ”) and '-' (move…

A Memory Matching Game in java code with a 4x4 grid of Squares that when you click on a square it shows a number. It would have to be 2 of each number 1-8 and if the two squares that are clicked match then the squares stay on the grid. If they do not match after picking 2 squares they flip back over
# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…
Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information Heat flow through a rod can be simulated fairly easily in a computer program. We can simulate the rod using an array of temperatures. The rod begins all at the same temperature (user determined), but holding some position(s) of the rod at constant temperature (holding a match or ice cube to the rod) provides a [set of] heat source(s) (or sink(s)). To update the temperature at each time step (second?), you take the average of the positions on each side from the previous time step (and at the current position). For instance, if the following was the initial state of the rod: +------+------+------+------+------+------+------+------+ | 10 | 10 | 10 | 10 | 10 | 10 | 10 | 10 | +------+------+------+------+------+------+------+------+ And then the user specifies that there is a heat source at the left end of 100 degrees:…
