CONSTRUCTOR & DESTRUCTOR

 

WRITE A PROGRAM IN CLASS THAT CAN STORE AN INTEGER ARRAY OF DIFFERENT WITH FOLLOWING MEMBER FUNCTIONS
A) CONSTRUCTOR WITH ARRAY SIZE =0
B) COPY CONSTRUCTOR
C) DESTRUCTOR

#include <iostream>

class arr{
	int a[100],size;
public:
	arr(){
		std::cout<<"CONSTRUCTOR INITIALIZED ARRAY SIZE TO 0";
		size=0; a[size];
	}

	arr(arr &x);

	~arr()
	{
		std::cout<<std::endl<<"DESTRUCTOR INVOLVED ~~ FREE MEMORY";
	}

};

 arr::arr(arr &x)
{
	std::cout<<std::endl<<"COPY CONSTRUCTOR INVOLVED";
	size=x.size;
	a[size];
	for(int i=0; i<x.size; i++)
	{
		a[i]=x.a[i];
	}
}

int main()
{
	arr a1;
	arr a2(a1);
}

INPUT-OUTPUT:

CONSTRUCTOR INITIALIZED ARRAY SIZE TO 0
COPY CONSTRUCTOR INVOLVED
DESTRUCTOR INVOLVED ~~ FREE MEMORY
DESTRUCTOR INVOLVED ~~ FREE MEMORY
