What is more efficient to pass as a parameter--a pointer or an object? Why?..

Answer / amar

Passing a parameter by pointer is more efficient than
passing as object. When a parameter is passed as object
another of copy of the object is created on stack hence it
has two overheads, 1. it takes cpu cycle while creating
copy object 2. it takes memory on stack.

Passing the parameter through pointer could lead to a
situation where function can acciedently change the value
of the object.
