Is it possible to add a different number for each li created in a for?

I have a cookie in bootstrap and to call wordpress posts inside it, I have for inside <div class="carousel-inner"> .

The for can create the posts, but I am not able to include the indicators of each post (the balls that are below the carousel or <ol class="carousel-indicators"> ).

The structure of the indicators is: 

<ol class="carousel-indicators">
   <li data-target="#id_carousel" data-slide-to="0"></li>
</ol>

What I need is this data-slide-to , because it is being set to 0 for each post that was created, ie regardless of which one I click, the carousel returns to the first post.

What I have: 

<ol class="carousel-indicators">
   <?php for ($i = 1; $i <= NUMBER_OF_SLIDES; $i++) : ?>
      <li data-target="#carousel" data-slide-to="0" class="<?php echo ($i == 1) ? 'active' : ''; ?>"></li>
   <?php endfor; ?>
</ol>

The <li> are created within for , but I am not able to assign a number other than data-slide-to to every <li> created.

What I'm trying to do is to make the output of this for quit like this: 

<li data-slide-to="0">
<li data-slide-to="1">
<li data-slide-to="2">
...

Would that be? 

<?php for ($i = 0; $i <= NUMBER_OF_SLIDES; $i++) : ?>
      <li data-target="#carousel" data-slide-to="<?php echo $i; ?>" class="<?php echo ($i == 1) ? 'active' : ''; ?>"></li>
<?php endfor; ?>
