How do I get the position of an object in a 2D array in C++?

For an assignment I have to make an 8×8 grid, randomly place two or more Js in it, then run through it and say where each J is. I’ve gotten most of it, but whenever I try to output the positions, it outputs garbage instead.

This is what I have right now:

#include <iostream>
using namespace std;

int main()
{
    char array[8][8] = {
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
        {'O', 'O', 'O', 'O', 'O', 'O', 'O', 'O'},
    };
    srand(time(NULL));

    for (int i = 0; i < 2; i++) {
        array[rand() % 5][rand() % 5] = 'J';
    }


    //print the grid
    for (int i = 0; i < 8; i++)
    {
        for (int j = 0; j < 8; j++)
        {
            cout << "\t" << array[i][j];
        }
        cout << endl;
    }

    for (int i = 0; i < 8; i++)
    {
        for (int j = 0; j < 8; j++)
        {
            if (array[i][j] == 'J')
            {
                cout << "Jewel found at " << array[i] << ", " << array[j] << endl;
            }
        }
        cout << endl;
    }
}

I know it’s probably because it’s outputting the entire row/column it’s at, but I’m kind of stupid and can’t think of how to make it do what i want.

I was hoping it would just output the coordinates but i got some other stuff instead

>Solution :

Your cout statement that is printing a found position is wrong. It should be printing the values of i and j themselves, but instead you are printing the memory addresses of the array elements which are held at indexes i and j.

IOW, change this:

cout << "Jewel found at " << array[i] << ", " << array[j] << endl;

To this instead:

cout << "Jewel found at " << i << ", " << j << endl;

Also, your rand() expressions should be using % 8 instead of % 5.
