Create a class Armstrong and include startnumber and endnumber as data member and aslo include member function findArmstrongNumbers() to find all the Armstrong numbers between startnumber and endnumber. If sum of cubes of each digit of the number is equal to the number itself, then the number is called an Armstrong number. (Implement the concept of class and objects)

, An organization has been assigned the prefix 212.1.1/24 (class C) and wants to form subnets for four departments, with hosts as follows:

a.      A 75 hosts

b.     B 35 hosts

c.      C 20 hosts

d.     D 18 hosts

           There are 148 hosts in all.

           a) Give a possible assignment of subnet masks to make this possible.

           b) Suggest what the organization might do if department D grows to 32 hosts.

Sol:

(a) Giving each department a single subnet, the nominal subnet sizes are 27 ,26 ,25 ,25

respectively; we obtain these by rounding up to the nearest power of 2. A possible

arrangement of subnet numbers is as follows. 

Consider a publishing company that markets book . Create a base class Publication that stores the title (a string), number of copies sold and price(type float) of a publication. Class Book which adds a page_count(int) is derived from the class Publication. Each class should have get_data() function to get its data from the user at the keyboard. Write the main() function to test the Book and publication classes by creating instances of them asking the user to fill in data with get_data() and then displaying it using put_data().
