______ is a testing technique in which one attempts to run through all possible combinations of branch paths through the code.

Testing a program based on varying input values without knowing what the code looks like is called _____.

With _____ testing, you make sure that every instruction in the code is executed at least once.

All instance methods in C++ have a hidden first argument named ________.

In a linked list, the last node's next point always has the value ______.

In the LinkedList class, the hidden argument's type is ______.

Rewrite the following line for a linked list rather than an array.
Make sure you use getters and setters. Assume the same Node class as we saw
in lecture. I have started it for you.
for(int i=0;i10) for(Node *tmp; ; )

--------------------

Node::Node()

{

   data = 0;

   next = NULL;

}

Node::Node(int d)

{

   data = d;

   next = NULL;

}
