You've declared a local array named "int" which has nothing in it.

This is inside a function named "int".

You're iterating on the empty local array.

You also have a global array named "int".

I suggest that you use different names for your stuff.  This will help
you avoid a lot of problems.  Having a global variable, a local variable,
and a function all sharing the same name (and a name which is actively
*misleading* given that one of the arrays does not, in fact, contain
integer values) is not helping you.
