MindTree OOPS Quiz 1

If we omit mentioning the function Object() { [native code] } and assignment operator, the compiler can write them automatically.

Virtual constructors do not exist as it is meaningless for c++ compiler to create an object.

Constructors are automatically called by a new operator.

Constructor can be private that's why this statement is wrong.

A copy constructoris called when an object is passed by value.

Abstract class relies upon its sub-classes for complete implementation of its methods

Object class is the superclass of every class in Java

Class getclass() is used to determine an object's class at runtime.

In class, only all the listed items except class will be declared.

Class A { int x; }; is a valid class declaration.

Protected keywords are used to control access to a class member.

The state of an object that we create from a class with no members is empty.Even though that object doesn't perform any actions, the compiler still assigns it a unique address.The smallest amount of memory that may be accessed at an object address position is one byte since computer memory is always organised in terms of bytes.

As a result, an object of the empty class is 1 byte in size.
