Program doesn't work

[FrankSquirel]

Hey, I am trying to make a program which simulates a game which works like this:

The object of the game is to reach 21 points first without going over. When both players reach 21 on the same number of rolls, or if both players “bust” on the same number of rolls, a tie occurs. If only one player "busts" in a roll, that player loses.

When I run the program (on compilr.com), I get this error after I input how many games I want to play:

bash: line 1:   278 Segmentation fault      ./program

Here's the code for my program

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <iomanip>
#include <iostream>

using namespace std;

void playGame();

int main()
{
    int games; 
    int gNumber;
    
    cout << "How many games do you want to play? ";
    cin >> games;
    
    for (gNumber = 1; gNumber <= games; gNumber++)
    {
    	cout << "\n    *** GAME " << gNumber << "***    ";
        cout << "\nRoll  Player 1  Player 2";
		playGame();
    }
    
}
void playGame()
{
    int points[2][21];
	int p1 = 0, p2 = 0;
    int i = 1;
    
    srand ( time(NULL) );
    
    do
    {
    cout << "\n " << i;
        
    points[1][i] = p1 + rand() % 6 + 1;
    points[2][i] = p2 + rand() % 6 + 1;
    
    p1 = points[1][i];
    p2 = points[2][i];
        
    cout << setw(8) << points[1][i] << setw(8) << points[2][i];    
    
    i++;
    }
    while(points[1][i] < 21 || points[2][i] < 21);
    
}

Thanks!

Although you didn't really ask a question, try this:

#include <stdlib.h>
#include <time.h>
#include <iomanip>
#include <iostream>

using namespace std;

void playGame();

int main()
{
  int games; 

  srand ( time(NULL) );
  
  cout << "How many games do you want to play? ";
  cin >> games;

  for( int gNumber = 1; gNumber <= games; gNumber++)
  {
    cout << "\n    *** GAME " << gNumber << "***    ";
    cout << "\nRoll  Player 1  Player 2";
    playGame();
  }

}
void playGame()
{
  int p1 = 0, p2 = 0;
  int i = 1;
  do
  {
    p1 += rand() % 6 + 1;
    p2 += rand() % 6 + 1;

    cout << "\n " << i++;
    cout << setw(8) << p1 << setw(8) << p2; 
  }
  while( p1 < 21 and p2 < 21 );

}

It works! Thanks! But Im wondering, what was wrong with my program before?
