rand() not printing correct #s for dice?

[Nefeli]

Hello all,

I'm pretty new to C++. I've just done a ton of research to build a program that rolls 2 sets of dice 36000 times and then stores the different combinations into a 2D array. The first row is all the rolls from dice1 and the second row is the rolls from dice2.

The only problem I'm having at this point is that I can't keep the random numbers between 1 and 6 for the die. I've tried using rand() with and without the +1, and I've been unsuccessful at finding a solution to this so far. Any help (not too advanced, please) is appreciated.

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

int main(){   
   
   srand(time(0));
   int count = 0;
   const int column_size = 36;
   const int row_size = 2;
   int dice[row_size][column_size];
   
while (count<36000){
dice[rand()%6][rand()%6];
count++;   
}


   for(int row = 0; row<row_size; row++){
      for(int column = 0; column<column_size; column++){  //Printing the array
         cout<<dice[row][column]<<" ";
      }
      cout<<endl;
   }
   

   return 0;
}

I have also tried using this instead:

   while (count<36000){
      die1 = rand()%6+1;
      die2 = rand()%6+1;
   
      dice[die1][die2];
      count++;   
   }

First off line 15 is bogus. You're generating two indexes, each of which is from 0-5. (6x6).
However, your array is declared as [2][36].

Your declaration of your array (dice) doesn't match your problem statement.

rolls 2 sets of dice

That implies more than two dice. Did you mean a "a set of 2 dice"?

If you're trying to count how many times each combination comes up in 36,000 rolls, a simple 6x6 array is sufficient.

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <iomanip>
using namespace std;

int roll_die ()
{   return rand()%6;
}

int main()
{   srand((unsigned)time(0));
    int count = 0;
    int roll1, roll2;
    const int FACES = 6; 
    int dice[FACES][FACES];
   
    //  Initialize the array
    for (int i=0; i<FACES; i++)
        for (int j=0; j<FACES; j++)
            dice[i][j] = 0;
            
    while (count<36000)
    {   roll1 = roll_die();
        roll2 = roll_die();
        dice[roll1][roll2]++;  
        count++;   
    }

   for(int row = 0; row<FACES; row++)
   {    for(int column = 0; column<FACES; column++)
            cout << setw(6) << dice[row][column] << " ";
        cout << endl;
   }
   system ("pause");
   return 0;
}
