memory allocation for objects

0 votes
When we instantiate a variable in C++, such as int x within a function (i.e. x is a local variable), it is allocated on the process's stack.

However, if we do int *x= new int, heap space is granted. So here are my inquiries:

What about objects of multiple classes (c++ classes or user specified classes)?

Where are their items created?

As an example:

Employee is a class, and we declare it emp;.

Is emp allocated space on the stack or on the heap?

Do all four cells of a get stack space if the declaration int a[4] is within a function?
