1000 dice output 2-12 weird negative number

[Flynn Rhodes]

I wrote a program to output 2 through 12 of 1000 dice rolls and it does everything it needs to do but it is putting out a large negative number after outputting 2-12 for some reason.

 // Two Dice.cpp : This file contains the 'main' function. Program execution begins and ends there.
//

#include "pch.h"
#include <iostream>
#include <array>
#include <cstdlib>
#include <ctime>
using namespace std;


int main()
{
	int roll{ 0 };
	int arolls{ 0 };
	int croll[11];
	srand(static_cast<unsigned int>(time(0)));
    std::cout << "Prepare for 1000 dice rolls!\n"; 

	for (int i{ 0 }; i < 1000; i++)
	{
		roll = 1 + rand() % (6);
		arolls += roll;
		if (i > 1 && i < 13)
		{
			croll[i - 2] = roll;
		}
	}
	cout << "\nThe following are rolls 2-12.\n\n";
	for (int i{ 0 }; i < 12; i++)
	{
		cout << " " << croll[i];
	}
	arolls = arolls / 1000;
	cout << "\n The average of 1,000 rolls is " << arolls << " .\n\n";
}

You only filled array elements croll[0] to croll[10].
Then you tried to print out croll[0] to croll[11].

32:25 warning: iteration 11u invokes undefined behavior [-Waggressive-loop-optimizations]

On last iteration the i==11 on line 32.
The croll has only 11 elements.
There is no element croll[11].

You print content of memory that is after the array croll as if it were an int.
We have no idea what that memory has.

Thank you for the help that was the problem!
