重置第一个循环后的值井字c++

游戏不会重置上次游戏的输入。它有第一个游戏的输入，不会在询问用户是否想再次玩的循环中重置。我尝试制作一个void函数，通过使用两个相同的数组来重置代码的值，但它仍然不起作用。请帮忙，因为我对c++还很陌生。

#include <iostream>
using namespace std;
char matrix[3][3] = { '1', '2', '3', '4', '5', '6', '7', '8', '9' };
const char matrix2[3][3] = { '1', '2', '3', '4', '5', '6', '7', '8', '9' };
char player = 'X';
int n;
int xscore = 0, oscore = 0, gamenum = 1;
void Draw()
{
system("cls");
cout << "T i c T a c T o e" << endl;
cout << "Game #" << gamenum << " Score: X - [" << xscore << "] O - [" << oscore << "]" << endl;
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 3; j++)
{
cout << matrix[i][j] << "   ";
}
cout << endl;
}
}
void Input()
{
int a;
cout << "It's " << player << " turn. " <<"Press the number of the field: ";
cin >> a;
if (a == 1)
{
if (matrix[0][0] == '1')
matrix[0][0] = player;
else
{
cout << "Number is already filled try again." << endl;

正如您所看到的，gamreset((函数不起作用。我尝试了很多方法来找出如何重置它，但仍然没有成功。
