in c++ write a program that will read multiple .txt files with words and store them in linked list within linked list without overriding them. For example, I am reading a script file that contains txt files such as these Input.script: one.txt: a b c d e f g two.txt: A B C D E F G

I need to make a linked list within a liked list, For example, one -> two -> NULL and whithin node "one" i have a linked list: a -> b -> c -> d -> e -> f -> g -> NULL and also within node "two" i have a linked list: A-> B-> C -> D -> E -> F -> G -> NULL
