Jquery hide() all elements with certain class except one

<div class='hide'>A</div>
<div class='hide'>B</div>
<div class='hide' id='1'>C</div>

I have a function called showOne which should hide all elements and then show the one with id='1'.

function showOne(id) {
// Hide all elements with class = 'hide'
$('#'+id).show();
}

How do I hide all elements with class = 'hide' in jquery?
