4. The following is one possible answer:
   0: // Ex1504.cpp
   1: #include
   2: using namespace std;
   3: class myClass
   4: {
   5: public:
   6: myClass();
   7: ~myClass();
   8: void ShowMember();
   9: static int GetStatic();
   10: private:
   11: int itsMember;
   12: static int itsStatic;
   13: };
   14:
   15: myClass::myClass():
   16: itsMember(1)
   17: {
   18: itsStatic++;
   19: }
   20:
   21: myClass::~myClass()
   22: {
   23: itsStatic--;
   24: cout << “In destructor. ItsStatic: “ << itsStatic << endl;
   25: }
   26:
   27: void myClass::ShowMember()
   28: {
   29: cout << “itsMember: “ << itsMember << endl;
   30: }
   31:
   32: int myClass::itsStatic = 0;
   33:
   34: int myClass::GetStatic()
   35: {
   36: return itsStatic;
   37: }
   38:
   39: int main()
