In C

Write a function called copyList(), which makes a "deep" copy or complete copy of one singly linked list. The copy must contain the data in the same order as the orginal list. The function should accept two parameters: a pointer to the source list and a pointer to the copy list. You need to decide if the pointers are single indirection (*) or double indirection (**). The function should not return a value. Note: a "deep" copy implies that new dynamic memory is allocated for each node in the copy list. You should NOT just do the following:

copyList = sourceList;

You may not assume that a makeNode() function exists. Assume the following node definition:

typedef struct node { int data; struct node *pNext; } Node;

Be sure to write out the function header.
