Primary expressions needed !!

[Nandi]

hi ! i cant seem to find the problem in the code. The errors are:
39 primary-expression before "double"
39 expected primary-expression before "char"
39 expected primary-expression before "unsigned"

#include<iostream>

It'd be helpful if you used code tags so I knew where the line numbers were.

When you call a function, you don't include the parameter types in the call.
