Name: _Professor Wolfe____________ Quiz 3 - Pointers and Linked Lists 1. Consider the following block of code: int workingNumber = 10; int* simplePointer = &workingNumber; int** pointerPointer = &simplePointer; a. Create a pointer called myPointer and make it point to workingNumber via simplePointer (i.e. do not write “workingNumber” in your code) int* myPointer = simplePointer; b. What variable would (*pointerPointer)++ increment? By how much? It would increment simplePointer by 4 bytes (i.e. sizeof(int)). c. What variable would (**pointerPointer)++ increment? By how much? It would increment workingNumber by 1. 2. What is a difference in how an array is stored in memory vs. a linked list? An array is always stored in consecutive memory locations, usually on the stack. A linked list can be stored across distant memory locations, always on the heap. 3. For int* ptr = NULL, what would cout operator: cout data); cout
