User Defined DataType

The data type is a format to store data that contains a particular range or type of value. It specifies which type of value a variable should have. In other words, a data type describes the type of data that variables can store. When a program stores data in the variables, then every variable needs to be assigned value that falls within the range of its data type. The following are some of the data types:

USING java: Create a simple Tic Tac Toe game designed for one player (against computer). you will need to create arrays and functions to complete this program. The first screen should ask the user for his name, print a welcome message, and display an empty 3x3 Tic Tac Toe board. Then, the program should ask the user to put the coordinates of his move. once the user enters the coordinates, the program should respond accordingly with a print of the user's move and the computer's move. this should go on until a winning pattern is found. Key steps: Game board is designed, user inputs taken and marked on the board, validate the inputs that no two inputs at the same place and out of range, check the winner/loser and complete the game.
In C# Use a one-dimensional array to solve the following problem. Write a class called ScoreFinder. This class receives a single dimensional integer array representing passer ratings for NFL players as an argument for its constructor. The test class will provides this argument. The test class then calls upon a method from the ScoreFinder class to start the process of finding a specific rating, which will be provided by the user. The method will iterate through the array and find any matching values. For all the matches that are found, the method will note the index of the cell along with its value. At completion, the method will print a list of all the indices and the associated scores along with a count of all the matching values.

Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //…
