3. You can’t assign a value to a constant object, and you can’t reassign a constant
   pointer. This means that lines 6 and 8 are problems.


4. The following is one possible answer. Note that this is a dangerous program to run
   because of the stray pointer.
   1: int main()
   2: {
   3: int pVar;
   4: pVar = 9;
   5: return 0;
   6: }


5. The following is one possible answer:
   1: int main()
   2: {
   3: int VarOne;
   4: int pVar = &varOne;
   5: pVar = 9;
   6: return 0;
   7: }


6. The following is one possible answer. Note that you should avoid memory leaks in
   your programs.
   1: #include
   2: int FuncOne();
   3: int main()
   4: {
   5: int localVar = FunOne();
   6: std::cout << “The value of localVar is: “ << localVar;
   7: return 0;
   8: }
   9:
   10: int FuncOne()
   11: {
   12: int pVar = new int (5);
   13: return pVar;
   14: }


7. The following is one possible answer:
   1: #include
   2: void FuncOne();
   3: int main()
   4: {
   5: FuncOne();
   6: return 0;
   7: }
   8:
   9: void FuncOne()
   10: {
