How To Print Fibonacci Series In C++

This is a example of how to print Fibonacci series in c++.


#include<stdio.h>
#include<conio.h>
#include<iostream.h>
class fibbonacci
{
int a,b,s;
public :
fibbonacci() //constructor
{
a=0;b=1;
}
void nextstep()
{
s=a+b;
b=a;
a=s;
}
void display()
{
cout<<"\t"<<s;
}
};
void main()
{
fibbonacci f1;
int n,i;
clrscr();
cout<<"\n\nEnter NO :";
cin>>n;
for(i=0;i<n;i++)
{
f1.nextstep();
f1.display();
}
getch();
}
