The term "destructor" made me believe this question is related to .Net languages.
A destructor is to destroy an instance of object. If it is available at static/class level, what is it going to destroy? The entire class, so the class no longer available? Thus, semantically, destructor should be an instance method.
Constructor is on the opposite end of the life cycle of an instance.
However, in .NET, a static constructor is allowed. Personally, I call this static constructor as a class initialization method. This method will be invoked by the .net framework only once when the class is loaded into the application domain.
With the similar concept, there should be a "finalizer" of the class when the class is unloaded out of the application domain. But wait, does a class ever go out of the application domain once it's loaded? Yes, only at the termination of the application! Currently a class cannot be unloaded explicitly in codes and thus no point to have a static finalizer.
What else can I help you with?
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.
What types of functions cannot be made virtual?
Static member functions, member function templates and constructors cannot be virtual.
What is the difference between constractor and distractor?
A constructor is a method in a class that is called when an object is created to initialize its state. A distractor, on the other hand, is not a commonly recognized term in the context of programming. It is possible you may mean "destructor," which is a method that is called when an object is destroyed to clean up resources before the memory is deallocated.
Why cannot a dime be made to stick to a wall using static electricity?
Too heavy.Too heavy.Too heavy.Too heavy.
What is a sentence for static?
The static electricity made my hair stand on end.

Explain the concepts of constructor and destructor Do you have to declare a constructor every time you create a class?
we cover constructors and destructors for C++ objects. Constructors give a means to initializing newly created objects and can be overloaded. Destructors offer a way to perform clean up on an object just before it is destroyed; a class can have at most one destructor. Together constructors and destructors provide a method of encapsulating the lifespan of an object. Although we have not done anything useful with destructors so far, we will see that they are extremely useful as our programs get more complex.In mathematics, an ordered list numbers is called a sequence. Sequences come in many types, but we can model a generic sequence with a class. Sequences can be of any length, but we will put a limit of 100 terms on our sequences for this first example:The code above describes a sequence class with two constructors, a member function, and two data members. The first constructor is a default constructor, which creates a sequence with no terms in it. The second constructor takes an array of terms and a length; the terms are copied from the array to the sequence via a for-loop. The member function outputs the length of the sequence and then all of the terms-a check is made internally to assure that sequence has at least one term before outputting them. The data members are the length and an array of doubles to hold the terms.In this main function, we create two instances of our sequence object and call Print() to output the sequences to the console window.
What kind of rules did Hammurabi make?
Some rules that Hammurabi made were if a building were to fall and kill it's owner, the constructor would be sentenced to death, and if the building killed the owner's son, the constructor's son would be sentenced to death
Which country was the Bunsen burner made?
Robert Bunsen (designer) and Peter Desaga (constructor) of Bunsen burner were Germans.
Characteristics of constructor?
Contains an access modifier followed by the name of the class and some parameters. More specifically: public class MyClass { //Constructor public MyClass() { } }
Why do you use the word static to describe static electricity?
Static means it doesn't move. This is essentially what static electricity is, a charge tht has no current. It is made by the transfer of electrons, as a pose to a cell or battery.
Can a static function be made virtual?
No. Virtual functions are invoked according to the runtime type of the object. That is; the most-derived override is automatically invoked even when the runtime type of the object cannot be determined at compile time. This is achieved through the object's virtual table. Static methods do not have any object associated with them; they can be invoked even when no object of the type exists. Without an object, there can be no virtual table. Thus static functions cannot be virtual. They are mutually exclusive concepts.
