17 .a. Write a C++ program to generate Fibonacci series using
constructor and destructor.
#include<iostream.h>
#include<conio.h>
class fib
{
int n,c,i,a,b;
public:
fib();
~fib()
{
cout<<"destructor is called";
}
};
fib::fib()
{
a=0;b=1;
cout<<"enter any no";
cin>>n;
cout<<"fibnocci series:\n";
for(i=0;i<n;i++)
{
if(i<=1)
{
c=i;
}
else
{
c=a+b;
a=b;

b=c;

cout<<c<<"\n";

void main()

fib ff;
getch();
}
b) Write a JAVA program with two packages namely decrement and
arithmetic operators and import these packages in a main class and show
the result.
NOTE:
1.inside bin create one folder: “arithmetic”
2. save the package arithmetic as “ addsub.java”.
3.similarly inside bin create another one folder: “decrement”
4. save the package decrement as “dec.java”.
5. In bin save the “main program” as sample1.java.
6. compile the program as: javac sample1.java
7. run the program as: java sample1
Package arithmetic;
public class addsub
{
int a=15,b=10,c,d;
public void print1()
{
c=a+b;
d=a-b;
System.out.println("sum="+c);

System.out.println("sum="+d);
}
}
package decrement;
public class dec
{
int a=15,c;
public void print2()
{
c=--a;
System.out.println("decrement="+c);
}
}
main program:
import arithmetic.addsub;
import decrement.dec;
class sample1
{
public static void main (String args[])
{
addsub x=new addsub();
dec y=new dec();
x.print1();
y.print2();
}
}
