DEFINE THE PROBLEM:
Write a Tic Tac Toe program that inputs the player’s names and then asks if you want to play again. It displays a score board at the end of the game.

OUTLINE THE SOLUTION: INPUT | PROCESSING | OUTPUT | Name of Player 1 | Names of Both players is inputted | Score board of who won, lost or any draws | Name of Player 2 | Player 1 makes the first move by choosing a number in the box then [X] will replace the chosen number | | Numbers on each box | Player 2 makes the second move by choosing a number in the box then [O] will replace the chosen number | | | If either of the players win, they receive a point in the score board | | | If it is a draw, the score board will display it | |

DEVELOP AN ALGORITHM: 1. Insert name of player 1 [X] 2. Insert name of player 2 [O] 3. Players choose the number of the box they want to input their letter in. 4. Once then choose the number they inputted their designated letter will replaced the number in the box 5. These steps are repeated as it is each player’s turn 6. The game will end until someone wins or it becomes a draw 7. The Score board will be displayed at the end
TEST THE ALGORITHM: 1. Name of Player 1: Flor 2. Name of Player 2: Karla 3. Flor chooses number 3 and is replaced by [X] 4. Karla chooses number 9 and is replaced by [O] 5. Each player goes until someone wins 6. Karla wins and the score board is displayed showing her as the winner.

CODE THE ALGORYTHM:
#include <iostream>
#include <string> void boardGame(); void next(); bool end(); char name();
