Tic Tac Toe c++ game project source code and documentation ~ C++ Programming Tutorial for Beginners

Here we will learn how to develop a tic tac toe multiplayer game project in С++ programming language with source code

Introduction
Let's assume you are a beginner in the c++ programming language and looking for a detailed guide with source code for the tic tac toe game.

This post will definitely help you to guide the complete process of development with a detailed explanation of code.

This C++ Game project is developed using C++ code blocks IDE. It has a defined board size of 5X5 with two modes.

1. Player vs Player. 2. Player vs Computer

C++ Concepts used in this c++ code project:

Variables
Two-dimensional Arrays (2D arrays)
Nested for loop
if else statement
functions

Code Explanation
In this c++ game, there are 5 global variables and 11 functions. Every function defines a separate different action in the game. The practice of defining functions for a separate action or related work always helps to keep the code clean, readable, and also trackable.

Variables
#define BoardSize 5
char Player1Move = 'X';
char Player2Move = 'O';
int p1 = 1;
int p2 = 2;

Functions

void menu();
void printBoard();
void input(int);
void player1();
void player2();
void p2p();
bool check();
bool defend(int, int, int);
bool attack();
void computerMoves(int);
void p2c();

2D Arrays

char board[BoardSize][BoardSize];

int b[BoardSize][BoardSize] = { 0 }; How code works?
"board" and "b" are two arrays, the board represents X for player 1 and O for player 2. 'b' is used only in player vs Computer game represents 1 for the first player and 2 for the second player which helps to build logic for computer moves.

Global variables description

BoardSize defines the tic tac toe game board size of 5
player1Move defines the symbol for player 1 which is 'X'
player2Move defines the symbol for player 2 which is 'O'
p1 represents value for the first player, it will be 1 or 2
p2 represents value for the second player, it will be 1 or 2
p1 and p2 are the variables that help to build the logic for the player to computer module
player will select as a 1st or 2nd turn

Functions description

menu
simple menu function shows and manage three options

player vs player
player vs computer
exit
according to the user choice call-related function.

printBoard
print the 5-by-5 board on the console.

input(int)
Takes input from user in both cases, player to player(form both players) and in the player to computer(only form player).
Asks the user to enter row number and column number for example 1 and 1 mean first cell of the board

player1
Calls in the case of player to player for player 1 move simply clear the screen first and then print the marker sign of player and then call above described input function.

player2
Calls in the case of a player to player for player 2 move simply clear the screen first and then print the marker sign of player and then call above described input function.

p2p
Calls player1 and player2 functions one by one and calls check function after every turn of the player e.g check function call when player1 place his/her marker on the board.

check
Checks the status of the game after every placement of the new marker this function will return true when all marks of the same type are in any row, column, or diagonally, otherwise, this function will return false.

defend
This function is for computer vs player move and called for computer move in this function computer will check the first all rows, columns and diagonals.

If the computer is having a possible winning move. Take the step and wins and also Checks if the player (opponent) has a possible winning move, takes a step to block the player.

attack aka Attacking move
Take a step such that it has winning possibilities in the next moves. place the marker in such a row or column which contains computer's marker more.

computerMove
Calls first defend function, check any possibility to win in this move, then check any possibility for the player wins.

If find any possibility to win or defend, place the marker at that place but if couldn't find then return false and if defend function return false then call the attack function.

if any cell is empty which may help the computer to win in the next moves then place a marker at that point but if not found then place any cell empty in the board.

p2c
first asks the user to play as a first or second player then according to the user's choice call the first turn for computer or player after every turn call the check function to determine the winning of any player, and when board filled, draw the game and return to the main menu.
