OOPS Write a program to demonstrate function definition outside class and accessing class members in function definition.

CODE:

#include<iostream.h>
#include<conio.h>

class fibo
{
public:
void fibonacci();
};

void fibo::fibonacci()
{
   int t1 = 0, t2 = 1, nextTerm = 0, n;

    cout << "\nEnter a positive number to calculate \nthe Fibonacci series upto entered number: ";
    cin >> n;
    cout << "\nFibonacci Series: " << t1 << ", " << t2 << ", ";

    nextTerm = t1 + t2;

    while(nextTerm <= n)
    {
        cout << nextTerm << ", ";
        t1 = t2;
        t2 = nextTerm;
        nextTerm = t1 + t2;
    }
}

void main()
{
clrscr();
fibo ob;
ob.fibonacci();
getch();

}
