c++ grid help

Hello Bellow i have a C++ grid code im using for a programm

--------
|X|X|X
|X|X|X
|X|X|X
--------
The output is like above where X is a random number put in by the "rand() % 3 + 1". now, my question is this. when the everyting is put out on the screen and numbers are in each box, how can i check to se if there is 3 of the same number in line with each other ??

int grid[3][3]; // grid
			grid[0][0] = rand() % 3 + 1; //Randomiserar
			grid[0][1] = rand() % 3 + 1; //Randomiserar 
			grid[0][2] = rand() % 3 + 1; //Randomiserar 

			grid[1][0] = rand() % 3 + 1; //Randomiserar
			grid[1][1] = rand() % 3 + 1; //Randomiserar 
			grid[1][2] = rand() % 3 + 1; //Randomiserar 

			grid[2][0] = rand() % 3 + 1; //Randomiserar 
			grid[2][1] = rand() % 3 + 1; //Randomiserar 
			grid[2][2] = rand() % 3 + 1; //Randomiserar 

			cout << "-Line1--Line2---Line3-" << endl; 

			for (int col = 0; col < 3; col ++)           
			{

				for (int row = 0; row < 3; row ++)
				{
					cout << "|  " << grid[row][col] << "  |";

I think you can do something like the following. I'm assuming tic tac toe style rules where diagonals count?

   int matches[8][3][2] = {{{0,0}, {1,0}, {2,0}}, {{0,0}, {0,1}, {0,2}}, {{0,0}, {1,1}, {2,2}},\
  {{0,1}, {1,1}, {2,1}}, {{0,2}, {1,1}, {2,0}}, {{0,2}, {1,2}, {2,2}}, {{1,0}, {1,1}, {1,2}},\
  {{2,0}, {2,1}, {2,2}}};
  
  int tmpTrips[3];
  int rowIndex, colIndex;
  
  int i, j, k;
  for (i=0; i<8; i++)
  { 
    for (j=0; j<3; j++)
    {
      for (k=0; k<2; k++)
      {
        if (k==0) rowIndex = matches[i][j][k];
        else colIndex = matches[i][j][k];
      }
      
      tmpTrips[j] = grid[rowIndex][colIndex];
      
    }
    
    if (tmpTrips[0] == tmpTrips[1] && tmpTrips[1] == tmpTrips[2])
    {
       printf("Three in a row!\n");
       break;
    }

  }

Not completely tested because I didn't feel like building the grid to fully test it. But it should be at least close.

 

Ye it was someting like that i was looking for! thank you, however im having really hard problems getting it to work with my code im adding the grid i have.

#include "stdafx.h"
#include <iostream>
#include <ctime>

using namespace std;
int main()
{
	//Deklarera variabler
	int j = 0, g = 0, h = 0, cpu, pengar = 0, vinst2, satsa, drabort, forlust, quit;
	srand(time(0));
	while(true){
		//om pengar är 0 startar spelet här, om pengar blir 0 under spelets gång börjar spelet om här
		if (pengar == 0)
		{
			//välkommnar spelaren samt frågar hur mycket han vill sätta in.
			cout << "how much do you wanna transfer from your bank? :"; cin >> pengar;
			cout << endl;

			//Random funktion för allas tärningar
	
			int grid[3][3]; // grid
			grid[0][0] = rand() % 3 + 1; //Randomiserar
			grid[0][1] = rand() % 3 + 1; //Randomiserar 
			grid[0][2] = rand() % 3 + 1; //Randomiserar 

			grid[1][0] = rand() % 3 + 1; //Randomiserar
			grid[1][1] = rand() % 3 + 1; //Randomiserar 
			grid[1][2] = rand() % 3 + 1; //Randomiserar 

			grid[2][0] = rand() % 3 + 1; //Randomiserar 
			grid[2][1] = rand() % 3 + 1; //Randomiserar 
			grid[2][2] = rand() % 3 + 1; //Randomiserar 

			cout << "-Line1--Line2---Line3-" << endl; 

			for (int col = 0; col < 3; col ++)           
			{

				for (int row = 0; row < 3; row ++)
				{
					cout << "|  " << grid[row][col] << "  |";
