Confusion with the auto type and other types

[Vesparo]

    constexpr size_t rowCnt = 3, colCnt = 4;
    int ia[rowCnt][colCnt] = {
        { 3, 6, 9, 12 },
        { 2, 4, 6, 8 },
        { 1, 2, 3, 4 }
    };
    
    for (auto &row : ia) // Right here
        for (auto col : row) // and here
            cout << col << endl;

What would I use instead of auto?

    for (int(&row)[4] : ia)    // row is a reference to an array of 4 int.
        for (int col : row)    // col is an int.
            cout << col << endl;

Would be equivalent.

Thanks for the response. I tried a similar approach but I had forgotten the parenthesis.
