Does any can help me with my program?

Why my while loop did not work?
this is a tic tac toe game, and it is my final exam in my school.

#include<iostream>
#include<cstdlib>
#include<string>
using namespace std;

void board(char square[9])
{
cout<<" Tic Tac Toe ";
cout<<" PLAYER 1(X) , PLAYER 2(o)\n\n";
cout<<square[0]<<"|"<<square[1]<<"|"<<square[2]<<endl;
cout<<"-------"<<endl;
cout<<square[3]<<"|"<<square[4]<<"|"<<square[5]<<endl;
cout<<"-------"<<endl;
cout<<square[6]<<"|"<<square[7]<<"|"<<square[8]<<endl;
}

string win(char square[9])
{
string win = "you win";
string keep = " PLease, keep input the number" ;


if(square[0]==square[1]&&square[1]==square[2])
return win;

else if(square[2]==square[4]&&square[4]==square[5])
return win;

else if(square[6]==square[7]&&square[7]==square[8])
return win;

else if(square[0]==square[3]&&square[3]==square[6])
return win;

else if(square[1]==square[4]&&square[4]==square[7])
return win;

return win;

return keep;

else
return keep;
}

int main() {

char square[9]={'1','2','3','4','5','6','7','8','9'}; // set the graph
int i=0,judge=0;
char mark1 = 'X', mark2 = 'O';
int w = 0,choice1 = 0,choice2 = 0;

cout << "if you can use X/O to make a line, you win";// rule of the game

while (i==9){

Your while loop only runs when i is 9, this will never happen because you i increment is within the while loop
