Help programming code problem TIC TAC TOE

[latbt1000]

Hello i was improvinsing a person's c++ program to make it have a single player option and a save function but after created the program it has some error that didnt show up in the compilers that i used.

When i run the 1 player mode it crashes in the middle of the game i think the error has to do whit the random function. Also when it saves into an output text file, it doesent save the date or the name of the player. Please tell me the solution to these problems thank you.(please keep it simple)

Code:









#include <iostream>
#include <fstream>
#include <time.h>
#include <cstdlib>
using namespace std;

char board[9] = { '1', '2', '3', '4', '5', '6', '7', '8', '9'};

string P2 = " ";
