looking for a model to recursively store data

[maharjun]

Hello people, im basically looking for a method to create a class called "real_no" which has the capacity to store numbers as they are.

i.e if the input is given as 2 + Root(2) then i should be able to store it as 2 + Root(2) and not 3.414. also, i would like it to be a structure where it is possible to carry the operations of + - * / with relative ease. with 2+ Root(2) the problem is pretty simple. but what of a number like

Root(2+root(109^{2/3})) here the problem starts getting a bit complex.

also,

[U]Root(2+root(109^{2/3}))[/U]
      23 + 55^{2/3}

also what if there is a root inside a root inside a root etc. like Root(3 - Root(4 + Root(5))) so basically im looking for a storge and retrieval structure which will enable me to operate such data.

if not then can anyone suggest a method by which recursive data storage can be acheived ion C++? i.e supposing I create a class of type A then i would like to store an object or a pointer or something to another object of type A as a data member of class A.

THANKS IN ADVANCE!!!

Im sorry if it appeared as if i was looking for a solution to my assignment. the assignment was actually just posted so that a person gets the idea of what im trying to do. it was basically to avoid any confusion that may have been created.what i was really interested in was whether there is any standard structure that people use to recursively store data. <see heading> for clarity in what i mean by recursive storage, please refer to last section of my post. i tried initializing a data-member within my class real_no of type real_no and it didnt compile. so i wanted to know if there is any trick to acheive the same or similar effect using another route?
