C++ program to print Fibonacci series by constructor

Program -

 

#include<iostream.h>

#include<conio.h>

class a

{

protected:

int a;

public:

a()

{

a=0;

}

};

class b

{

protected:

int b;

public:

b()

{

b=1;

}

};

class c:public a,public b

{

int c,a,b;

public:

c():a(),b()

{

c=a+b;

}

void print()

{

cout<<c<<"";

a=b;b=c;c=a+b;

}

};

void main()

{

clrscr();

int n;

cout<<"enter number of terms==>";

cin>>n;

c c;

cout<<"the series is==>0 1";

for(int i=1;i<=n-2;i++)

c.print();

getch();

}

Output - 

Enter number of terms== >9

The series  is == > 0 1 1 2 3 5 8 13 21
