4. If we create a stockDB class which stores variable number of stocks in a dynamic stock array. Complete the minimum stockDB.h class definition such that

stockDB frank(5), obama(700); // frank can have at most 5 stocks, obama 700 max

class stockDB {

5. (3pt) Write the implementation code (cpp) that supports frank = obama;

6. (3pt) Further assume that stock has operator< overloaded and there is a global swap(stock&, stock&) function. Complete the following implementation code for stockDB selection sort.

void stockDB::selectionSort() {

7. Add additional code below to cause a dangling pointer issue.

int * a = new int(5);

int * b = a;

8. Given the declaration int * d = new int[5]; Check ALL statements that prints out the address of the 2nd elements in d array

   1. cout << d + 1;

   2. cout << d + 4;

   3. cout << &d[1];

   4. cout << &d+4;

   5. cout << d++; // this is a bit tricky

9. Is the following code correct? If yes, whats the output? If no, whats wrong?

int *p; //Line 1

int *q; //Line 2

p = new int; //Line 3

*p = 43; //Line 4

q = p; //Line 5

*q = 52; //Line 6

delete q; //Line 7

cout << *p << " " << *q << endl; //Line 8
