What you're trying to do here:

C++ Syntax (Toggle Plain Text) 
  1. If(ptr->info==item)
  2. {
  3. int Count_Max(node_ptr&q,int x)
  4. {

is wrong. You can't declare a function inside another function.

Are your really using a linked list or did someone just give you that code?

He already has. You can't declare a function inside a function.
