Constructors and destructors

Question

Write a program to show that, the constructor and destructor functions of a globally declared object are the first and last functions, respectively to be called in a program.

Answer 1

using namespace std;

#include <iostream>

class X

{

private:

int x;

public:

X(int X)

{

this->x = X;

cout << "X constructor : x = "<< this->x << endl;

}

~X()

{

cout << "X destructor : x = "<< this->x << endl;

}

int Get() { return(x); }

};

X globalX(5);

int main()

{

//globalX constructor with X=5 will get called first

X localX(3);

// globalX destructor with X=5 will get called last

}
