C++ Program for Fibonacci series using constructor

Fibonacci Series:1 1 2 3 5 8 13 21 34 55

//SOURCE CODE:using constructor.....

#include<stdio.h>

#include<conio.h>

#include<iostream.h>

class fibo{

int a[100];

public:

fibo_show(int n);

}b1;

fibo::fibo_show(int n)

{a[0]=1;

int i;

a[1]=1;

for(i=0;i<n-2;i++)

{a[i+2]=a[i]+a[i+1];

 }

 for(i=0;i<n;i++)

 { cout<<a[i]<<"\t";

 }

}

main()

{int i;

OUTPUT:

enter the number of terms of fibonacci series
