Jquery, for loop shows all

$("#button").click(function () {
    var pp = []
    var ing = []

    for (var q = 1; q <= 6; q++) {
        pp[q - 1] = $('input[name=P' + (q) + ']').is(":checked");
        ing[q - 1] = $('div#ingp' + (q) + '').show();
    }

    for (var q = 1; q <= 6; q++) {
        if (pp[q - 1] == true) {
            ing[q - 1];
        }
    }
});

<div class="container" id="Boxx">
    <div id="ingrediënten">
        <div>
            <h1>Kies extra ingredienten</h1>
        </div>
        <div id="ingp1"></div>
        <div id="ingp2"></div>
        <div id="ingp3"></div>
        <div id="ingp4"></div>

    </div>
</div>

So the problem I have is that when I look if one or more of P1 to P6 is check then it shows all 6 div with id ingp1 to ingp6. I want it to show ingp1 when P1 is checked, and ingp3 when P3 is checked. You get it. How do I do this (small thing I am only allowed to use javascript and jquery).
