In this article we will try to implement a CPP program to show how constructors are invoked in derived class. A C++ program is given below to demostrate how constructors are invoked in derived class.
Program is as follows:
#include <iostream>
using namespace std;
class A
{
protected:
int x;
public:
A(int p)
{
x = p;
}
};
class B : A
{
private:
int y;
public:
B(int p, int q) : A(p)
{
y = q;
}
void display()
{
cout<<"x = "<<x<<endl;
cout<<"y = "<<y;
}
};
int main()
{
B b(10, 20);
b.display();
return 0;
}
Output for the above program is as follows:
x = 10
y = 20
