C++ how to compare two objects of the same class

The equality operator will work on pointers regardless of whether you've implemented the equality operator for your class. If it's giving an error when used with pointers, then you're doing something wrong.

To define the equality operator as part of your class:

Code:

class test
{
   public:
   bool operator==(const test &t); // in this method, see if t is equal to *this.
}
