   This is one solution to the lab problem of fixing program bad.cpp.
   The syntax errors were caused by missing semicolons.  The logic
   error was that when PrintArray gets called, count no longer contains
   the expected value of 6.  One simple fix is to not use the global
   variable count.  It has been removed below.  Global variables are
   frowned upon anyway!

   This program prompts the user to enter integers into an array, where
   they are stored in backwards order from that in which they are 
   entered.  The list of numbers is then printed on the screen (in
   backwards order, of course, from the order in which they were entered).

   Tested with:
      Microsoft Visual C++ 6.0
      Microsoft Visual C++ .NET
      g++ under Linux

const int MAX = 6;

// int count;  Avoiding this global variable is one way to fix things.


void LoadArray(int a[]);    // leaving out the ; is a syntax error
void PrintArray(int a[]);   // this line had the same problem


int main(void)
   {
   int num[MAX];

//   count = MAX;  This line is no longer needed.
   LoadArray(num);
   PrintArray(num);

   return 0;
   }


/* Given:   a   Nothing.

            in backwards order from that in which they are typed in.
