In this article we will learn to implement a CPP program to illustrate the order of execution of constructors and destructors in inheritance. A C++ program is provided below to demonstrate in which order constructors and destructors are executed in inheritance.
Program is as follows:
#include <iostream>
using namespace std;
class A
{
public:
A()
{
cout<<"A's Constructor"<<endl;
}
~A()
{
cout<<"A's Destructor"<<endl;
}
};
class B : A
{
public:
B()
{
cout<<"B's Constructor"<<endl;
}
~B()
{
cout<<"B's Destructor"<<endl;
}
};
class C : B
{
public:
C()
{
cout<<"C's Constructor"<<endl;
}
~C()
{
cout<<"C's Destructor"<<endl;
}
};
int main()
{
C c;
return 0;
}
Output for the above program is as follows:
A's Constructor
B's Constructor
C's Constructor
C's Destructor
B's Destructor
A's Destructor
