The programming language is C++

File input begins:

XXVII 123 MCLXV 1975 

File input ends

How, would I put a Roman Numeral or an Arabic numeral as a node in a linked list without taking in the rest of the blank space of the line?

The file contains lines of either a Roman Numeral or an Arabic Numeral

The lines should follow this format :

Roman numeral field 15 characters -

Arabic numeral field 4 characters

If a line only contains a Roman Numeral it needs to be converted into an Arabic Numeral and vice versa( I have already done this part)

My question is how would I put a Roman Numeral or an Arabic numeral as a node in a linked list without taking in the rest of the blank space of the line?

I have seen the use of #include, but this doesn't work with the compiler used in class
