Question

In C# A Tic Tac Toe program that uses functions and arrays. The program should start by asking the player one for their name and then player two for their name. Then should print the board and ask the user what column and then what row they would like to put their x (or o, depending on the player) . Use the clear function to make it look as though the board is never repeating.. Thanks!
