Since "c" is a one character long string, v = StringTake[var,
{1}] returns the single character c and assigns it to v.

Simply doing

v = c

causes Mathematica to evaluate c to 3 and assign this to v.

But, since the above seems very obvious, I assume there is
something else you want to do here. If you provide more detail
as to your ultimate goal someone likely can give you a better answer.
