    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()

    OOPS Design the class Demo which will contain the following methods: readNo(), factorial() for calculating the factorial of a number, reverseNo() will reverse the given number, isPalindrome() will check the given number is palindrome, isArmstrong() which will calculate the given number is armStrong or not.Where readNo() will be private method.
