basic to high level oops question:( C++) i was asked to write some class and in that these questions were asked 1: different types of access modifiers, but the question was asked indirectly. like why did i write public, what is public.. what else can be there, what if i dont write public... 2: heap space vs stack space in oops implementation, new keyword importance, eg: what if i dont use new, where the instance would be created... and so on.. i dont remember other question
