why private destructor getting called when obj is created statically

[dearvivekkumar]

Hi

Why private destructor are getting called when I creates an object of class having private destructor? But not when I creates a normal object.

================================ CASE I ====================================

// myclass.h

#include <iostream>

class MyClass {
public:
    static MyClass& GetInstance();
    void Display();
private:
    MyClass();
    virtual ~MyClass();
};

MyClass::MyClass() {
    std::cout << "Constructor " << std::endl;
}

MyClass::~MyClass() {
    std::cout << "Destructor" << std::endl;
}

MyClass& MyClass::GetInstance() {
    static MyClass _instance;
    return _instance;
}

void MyClass::Display() {
    std::cout << "Hello" << std::endl;
}
// main.cpp

#include "myclass.h"
#include <iostream>

int main() {

    MyClass::GetInstance().Display(); //case1



    std::cout << "main finished!" << std::endl;

    return 0;
}

// output
Constructor 
main finished
Destructor.

================================= CASE II ====================================

// myclass.h

#include <iostream>

class MyClass {
public:
    void Display();
    MyClass();
    virtual ~MyClass();
};

MyClass::MyClass() {
    std::cout << "Constructor " << std::endl;
}

MyClass::~MyClass() {
    std::cout << "Destructor" << std::endl;
}

MyClass& MyClass::GetInstance() {
    static MyClass _instance;
    return _instance;
}

void MyClass::Display() {
    std::cout << "Hello" << std::endl;
}
// main.cpp

#include "myclass.h"
#include <iostream>

int main() {

    MyClass testObj;



    std::cout << "main finished!" << std::endl;

    return 0;
}

// Error

you cannot use a private function/destructor outside of the class. On line 23 you define the object inside [the member function] of the class
