A program that simulates the rolling of two dice with comments

Write a program that simulates the rolling of two dice. The program should use rand to roll the first die, and should use rand again to roll the second die. The sum of the two values should then be calculated. [Note: Since each die can show an integer value from 1 to 6, then the sum of the two values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 the least frequent sums.] The program should roll the dice 36,000 times. Use a single-subscripted array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable; i.e., there are six ways to roll a 7, so approxiamately one-sixth of all the rolls should be 7.

//this is my code somthing is wrong with it and im confused im not sure if I am doing the right thing
using namespace std;
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
   
    const int arraysize = 13;


    int die1[arraysize];
    int die2[arraysize];
     


    srand( time( 0 ) );


    for ( int roll1 = 0; roll1 <=36000; roll1++ )
        die1[ 1 + rand() % 6]++;
   
    for ( int roll2 = 0; roll2 <=36000; roll2++ )
        die2[ 1 + rand() % 6]++;
    for (int counter=0;counter<arraysize;counter++)
        counter[die1+die2]++;

   
    cout<<"sum of Faces"<<setw(13)<<"Frequency"<<endl;

    for(int face=2; face<arraysize;face++)

        cout<<setw(7)<<face<<setw(13)<<counter[face]<<endl;

        system("PAUSE");
        return 0;
    }
