OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Question: Write a program with C# to Simulate a game of tic tac toe. A game of tic tac toe has two players. A Player class is required to store /represent information about each player. The UML diagram is given below. Player -name: string -symbol :char Player (name:string,symbol:char) getName():string getSymbol():char getInfo():string The tic tac toe board will be represented by a two dimensional array of size 3 by 3 characters. At the start of the game each cell is empty (must be set to the underscore character ‘_’). Program flow: Your program must ask for each player’s name and their special symbol or character (usually an ‘X’ or ‘O’). Display each player’s name and symbol. The program must then display the board (the 2 dimensional array). The player whose turn it is has their name displayed and is asked for a row and column number to place their symbol. They can enter -1 -1 as the row and column number to quit. Repeat 2 and 3 until one player enters -1 -1.…Question: Write a program to Simulate a game of tic tac toe.
