Try this:

{assign var='c' value=0}
{assign var='c' value=$c+1}

The short form should work too, but you say it doesn't.

{$c=0}
{$c=$c+1}

But this doesn't work because you're using Smarty 2, right? Because in Smarty 3 it should work.

You can use expressions with the {assign} template function.

{assign var=c value=$c+1}

Or in its short form,

{$c=$c+1}

Try:

{assign var="c" value="`$something+$constant`"}

But usually the sense of template frameworks is to follow the mvc pattern. So all the logic is done in a controller. Or in the case of you some sort of php script. The view should not hold much logic(less logic better view code). So any sort of calculations should not be in a view. In mvc you will have however some sort of logic like iterations or link generation(through e.g. smarty plugins).
