...Now so what's the difference between passing an int datatype and object when its scope is just limited to the called function ?...

i was taught that both in java and c# objects are referenced types so when we do any operations on the object they get reflected to entire object wherever you access it

The above still gives the output as "Grade1Employee" why is it so?
