FM>Hey, Cliff and gang.  How's this?
Frank, it looks pretty good. You've got a functioning class!
FM>Too Borland spcific?
The only Borlandism is clrscr(), so that's not too bad.

Here is my version:
#include 
#include 
#include 
class crazyII
{
 private:
  int   pooky, kooky;
  float smoky;
 public:
  // Instead of an Install() function, I used a constructor. It is
  // just like your Install() except it is automatically called when
  // a crazyII object is created--so no c.Install(x, y, z); is needed.
  // You should use constructors for this reason.
  // Also notice I have given default values for each of the
  // arguments. C++ allows this in functions. That means you can
  // use this constructor to create crazyII objects by giving 0, 1,
  // 2, or 3 arguments. For the ones not given, the default value is
  // used. Note that you can only drop arguments from right to left.
  // You could not skip an int value and put a float for instance.
  crazyII(int p = 0, int k = 0, float f = 0.0f) 
  {
     pooky = p; kooky = k; smoky = f;
  }
  // Instead of a Display() function, I overloaded the << operator.
  // This is much more convenient. The notation is a little 
  // complicated to do this, but using the result is easy.
  friend ostream & operator << (ostream & os, crazyII & c)
  {
    // Given the output stream os, use its << operator to
    // display object c's members. 
    os << "Pooky = " << c.pooky << endl;
    os << "Kooky = " << c.kooky << endl;
    os << "Smoky = "
       << setiosflags(ios:: showpoint)
       << setprecision(2)
       << setw(2)
       << c.smoky << endl;
    return os;  // Return the reference to the ostream
  }
};
  
int main(void)
{
 crazyII c1;        // Create a crazyII with all default values.
 crazyII c2(25, 50, 3.1415);  // crazy II object with my values.
 clrscr();
 cout << c1;   // Use overloaded << to display c1
 cout << c2;   
 return 0;
}
