What is the order of constructors and destructors of object?
The order of constructors is determined by the sequence they are called in the code, starting with the base class constructor and moving to the derived class constructor. Destructors are called in the reverse order of constructors, starting with the derived class destructor and moving to the base class destructor.
When you move a file a copy of the file remains in the original location?
When you move a file, the file is physically transferred to a new location. There is no copy left in the original location, only the file in its new destination. If you want to keep a copy in the original location, you need to use the "copy and paste" function instead of the "cut and paste" function.
How much does a skid of copy paper weigh?
A skid of copy paper typically weighs around 1,500-2,000 pounds, depending on the paper weight and quantity.

How much does 1 sheet of copy paper weigh?
A standard sheet of copy paper typically weighs about 4.5 grams, which is equivalent to 0.01 pounds or 0.0045 kilograms.
How do you invoke the constructor function in c plus plus?
There is no such thing as a constructor function in C++ (constructors have no return value, not even void, and cannot be called like regular functions). Constructors are invoked rather than called directly, either by declaring a static variable of the class type, or via the C++ new operator.
When copy constructor is automatically invoked in object oriented programming?
A copy constructor is automatically invoked in object-oriented programming when a new object is created as a copy of an existing object. This typically occurs in scenarios such as passing an object by value to a function, returning an object from a function, or initializing a new object with another existing object. The copy constructor allows for the creation of a new instance that duplicates the state of the original object, ensuring that any dynamic resources are correctly managed.
Why base class constructor is first invoked in subclass constructor?
The base class constructor is invoked first when a subclass is instantiated, because the base class must be viable and consistent before the subclass constructor is fired.
What will be automaticlly invoked when an object is created?
The constructor.
Constructor cannot be virtual but destructor can be virtual justify?
bcoz constructor cant be invoked
How constructor automatically invoked?
when we create the object of that class
Does Java support copy constructor?
No. Java does not support copy constructor
Why pointer of constructor is made but not of destructor?
When a constructor is invoked dynamically, the new operator allocates the required memory, initialises it according to the constructor, then returns a pointer to the allocation. The destructor is invoked by deleting the pointer. It wouldn't make any sense to return a pointer from a deletion.
Discrbe breifly about Copy constructor overloading?
A copy constructor usually refers to a constructor which takes an object, and returns a copy of that object. I can think of no way to overload the constructor without changing its functionality.
When invoking a constructor from subclass its super class's no-arg constructor is always invoked?
Implicitly: (i.e., you do not code for it, but works as if you did)calling the no-argument constructor of the subclass, and there is no explicitly "redirect" codes.Explicitly:a constructor with base() / super() in the implementation, even that invoked constructor required some arguments.C# example: public SubClass(string whatever) : base() {//...}
What is the advantage of user-defined copy constructor?

Can you declare constructor as a private in c plus plus?
Yes. However, like any other private member, a private constructor can only be accessed by the class itself (typically via a static member function) or by one of its friends. There are very few cases where private constructors are appropriate, one of the most common being the need to suppress the compiler-generated copy construction of a base class. However, since C++11, suppressed constructors can simply be deleted, thus making error messages much more meaningful to users of your class. For example, instead of the following: class A { public: A (); // default constructor private: A (const A&); // suppress copy constructor (can still be invoked by the class and its friends) // ... }; You'd now use the following: class A { public: A (); // default constructor A (const A&) =delete; // suppress copy constructor (cannot be invoked at all) // ... };
