Consider the following C++ statements: struct nodeType { int info; nodeType *link; }; nodeType *head, *p, *q, *newNode; newNode = new nodeType; 1. Write C++ statement to store 50 in the info field of the newNode. 2. Write C++ statement to set the link field of the newNode to NULL. 3. Write C++ statement to make head pointer points to newNode. 4. Write C++ statement to delete the first node in the linked list. (the first and the only node in the linked list that you just added it in the previous questions.)

1.

newNode ->info = 50;

2.

newNode ->link = NULL;

3.

head = newNode;

4.

delete head;

Explanation:

1.

The C++ statement newNode ->info = 50; will perform a function of storing the number 50 in the info field of the newNode.

2.

newNode ->link = NULL;

This above written code will simply perform one function, and that is to set the link field of the newNode to NULL.

3.

When this C++ code is written

head = newNode; it will produce the output of making head pointer points to newNode.

4.

delete head; this statement performs the function of deleting the first node in the linked list.
