[HELP in S.O.S game win counts]

[kroragna]

Hello, my professor asked us to make an S.O.S game. My only problem is how can I check whether the p1 or p2 made an SOS. Can you give me a hint and also can you give me an advice to make my program more efficient and bug free. My friend told me to make void scorecheck1(int&player1score) and void scorecheck2(int&player2score). But I don't know what to put in that function. here are the codes.

 #include <iostream>
#include <cstdlib>
#include <windows.h>
#include <cstring>
#include <ctime>

using namespace std;
void game_start();
void start_up();
void game_board();
void scorecheck1(int&player1score);
void scorecheck2(int&player2score);
string player1,player2;
int player1score = 0;
int player2score = 0;
int i, turn1,turn2, j = 0;
int player1choice, player2choice;
string letter;
string board[64];


int main()
{
	start_up();
	return 0;
}
void start_up()
{
	system("color 0B");
	char choice;

	cout<<"\t\t =====    ======    =====\t\t\n";Sleep(250);
	cout<<"\t\t ||       ||  ||    ||   \t\t\n";Sleep(250);
	cout<<"\t\t ||       ||  ||    ||   \t\t\n";Sleep(250);
	cout<<"\t\t =====    ||  ||    =====\t\t\n";Sleep(250);
	cout<<"\t\t    ||    ||  ||       ||\t\t\n";Sleep(250);
	cout<<"\t\t    ||    ||  ||       ||\t\t\n";Sleep(250);
	cout<<"\t\t =====    ======    ===== \t\t\n";Sleep(250);
	cout<<"\t\t ======   ======   ======     =====   =====   ======        ======    ======\t\t\n";Sleep(250);
	cout<<"\t\t ||       ||  ||   ||            ||      ||       ||        ||   ||       ||\t\t\n";Sleep(250);
	cout<<"\t\t ||       ||  ||   ======  ==>   ||      ||   ======  ==>   ||====    ======\t\t\n";Sleep(250);
	cout<<"\t\t ||       ||  ||   ||            ||      ||       ||        ||   ||       ||\t\t\n";Sleep(250);
	cout<<"\t\t ======   ======   ======     =======  ====== ======        ======    ======\t\t\n";Sleep(250);
	
	
	cout<<"\t\tWelcome to the game of S.O.S!\t\t\n\n";Sleep(250);
	cout<<"\t\tThis game is brought to you BY:\t\t\n";Sleep(250);
	cout<<"\t\tJasper Adrian S. Escala\t\t\n";Sleep(250);
	cout<<"\t\tGelo M. Hubalde\t\t\n";Sleep(250);
	cout<<"\t\tPress any key to continute..\n\n";
	system("pause>0");
	system("cls");
	cout<<"Press Y if you like to start and N if you want to terminate.\n";
	cin>>choice;
	system ("cls");
