Adding variable(s) subscript to variable(s) for equation writing

https://dl.dropbox.com/u/92979563/checkss.png

Kindly see this image.
I am willing to get output somewhat like this.
It is having variable with variable subscript(s).
Can we write equations having variable subscripted variables and get user input in it using normal "cin" from the user, in c++ ?

If yes, kindly assist by giving how can we do so by displaying that text [preferred] or anything in random from your side via a program.


Best Regards.
yes it's possible, use unicode.

It's no different than writting this to screen:
"Fxk = Fzk + Uxk" and having the user enter values for each symbol.

Except that, instead of simply typing the chars from ur keyboard u'll have to dig for the corresponding unicode values for the chars u want to see.
