Member Insertion By Position

Modify the list class you created in the previous programming challenges by adding a member function for inserting a new item at a specified position:

void insert$($double $x,$ int pos$)$;

A position of $0$ means that $x$ will become the first item on the list, a position of $1$ means that $x$ will become the second item on the list, and so on$.$ A position equal to$,$ or greater than, the length of the list means that the $x$ is placed at the end of the list.
