tic tac toe in Dev-C++ 4.9.9.2
Hi I wrote a tic tac toe game that uses 2 human players. However, I want to re-write the game where it only need 1 human and the second player is the computer. The only problem is I don't know how to do that. If someone has some good tips, link, or anything that can help me would great. Thanks.
Here is my two player version
Code:
#include "simpio.h"
#include <stdio.h>
char matrix[3][3];//={0};
void board(void);
int main()
{
int m,n;
char ch='y';
char x='X';
char o='O';
char again;
while(ch=='Y'||ch=='y'){
for (m=0;m<3;m++)for (n=0;n<3;n++)matrix[m][n]= '\0';
int i,j,sum=0;
while ( sum < 10){
if (sum == 0) board();
printf("Player 1 is 'X': choose the row and column");
printf("\nRow : ");
i=GetInteger();
printf("\nColumn : ");
j=GetInteger();
for (; i>3 || i<1 || j>3 || j<1 ||('X'==matrix[i-1][j-1]||'O'==matrix[i-1][j-1]);)
{
printf("Sorry, but you gotta choose another place.\n");
printf("row : ");
i=GetInteger();
printf("column : ");
j=GetInteger();
}
matrix[i-1][j-1]='X';
sum++;
board();
//check if wins
if (matrix[0][0]=='X' && matrix[0][0]==matrix[1][1] && matrix[1][1]==matrix[2][2]) {printf("Player 1 wins");break;}
if (matrix[2][0]=='X' && matrix[2][0]==matrix[1][1] && matrix[1][1]==matrix[0][2]) {printf("Player 1 wins");break;}
if (matrix[0][0]=='X' && matrix[0][0]==matrix[1][0] && matrix[1][0]==matrix[2][0]) {printf("Player 1 wins");break;}
if (matrix[0][1]=='X' && matrix[0][1]==matrix[1][1] && matrix[1][1]==matrix[2][1]) {printf("Player 1 wins");break;}
if (matrix[0][2]=='X' && matrix[0][2]==matrix[1][2] && matrix[1][2]==matrix[2][2]) {printf("Player 1 wins");break;}
if (matrix[0][0]=='X' && matrix[0][0]==matrix[0][1] && matrix[0][1]==matrix[0][2]) {printf("Player 1 wins");break;}
if (matrix[1][0]=='X' && matrix[1][0]==matrix[1][1] && matrix[1][1]==matrix[1][2]) {printf("Player 1 wins");break;}
if (matrix[2][0]=='X' && matrix[2][0]==matrix[2][1] && matrix[2][1]==matrix[2][2]) {printf("Player 1 wins");break;}
if (sum == 9){printf("The game is over and no one wins"); break;} //sum=9 because there are only 9 boxes in the game
//player 2's turn
printf("Player 2 is 'O': choose the row and column");
printf("Row : ");
i=GetInteger();
printf("Column : ");
j=GetInteger();
for (;i>3 || i<1 || j>3 || j<1 ||('X'==matrix[i-1][j-1]||'O'==matrix[i-1][j-1]);)
{
printf("Sorry, but you gotta choose another place.\n");printf("row : ");i=GetInteger();printf("column : ");j=GetInteger();}
matrix[i-1][j-1]=o;
sum++;
//the play box
board();
//check if wins
if (matrix[0][0]=='O' && matrix[0][0]==matrix[1][1] && matrix[1][1]==matrix[2][2]) {printf("Player 2 wins");break;}
if (matrix[2][0]=='O' && matrix[2][0]==matrix[1][1] && matrix[1][1]==matrix[0][2]) {printf("Player 2 wins");break;}
if (matrix[0][0]=='O' && matrix[0][0]==matrix[1][0] && matrix[1][0]==matrix[2][0]) {printf("Player 2 wins");break;}

if (matrix[2][0]=='O' && matrix[2][0]==matrix[2][1] && matrix[2][1]==matrix[2][2]) {printf("Player 2 wins");break;}
}
printf("\nWould you like to play again??? (Y - N)\n");
ch=getchar();
}
getchar();
return 0;
}
void board(void)
{
//the play box
printf("\n\t\t 1 2 3\n");
printf("\t\t 1 %c | %c | %c\n", matrix[0][0],matrix[0][1],matrix[0][2]);
printf("\t\t ---|---|---\n");
printf("\t\t 2 %c | %c | %c\n", matrix[1][0],matrix[1][1],matrix[1][2]);
