Does the main bignum main program have to add, subtract, compare big numbers?
A. No. Now, “+” adds a big number to the queue, “-” removes one, and so on as the write-up describes. • Q. For the netnode program, how do we know who sent the message to a particular NetworkNode? We need to know that to print out the proper messages. A. Take advantage of the current assumption that NetworkNodes are paired (i.e., are neighbors of one another) in this assignment. • A few comments on writing a linked list… • To traverse the list, you just need a pointer to a node. Thus, traversing (as in when you print) requires no allocation. • You need to make sure you deallocate memory you allocate. This means if you remove a node from the list, you must deallocate it. You must also make sure you remove all memory still used by nodes in the destructor. • You cannot do things like access “nodePtr->next” unless you are certain nodePtr is not NULL. One case where this might be a problem is when the list is empty, but others may occur depending on how you write your methods. • Q. For th
