I have a problem with my code and I need some help to figure out the code. The purpose of the code is to enter the grades and display the overall average.  Also to display the highest grade entered.  the output of the code should show the overall average of the grades entered and the highest grade entered... my biggest problem is I can't figure out the code to display the hightest grade ... Please give suggestions or please fix the code/
thank you
 
 
 
#include <stdio.h>
#define HIGHEST 90
int highest[HIGHEST];
int  main()
{
   float average;              /* new data type */
   int counter, grade, total, highest;
   /* initialization phase */
   total= 0;
   counter= 0;
   highest=80;
   /* processing phase */
   printf( "Enter grade, -1 to end: " );
   scanf( "%d", &grade );
   printf("High grade");
   scanf("%d", &highest);

   while ( grade != -1 ) {
      total = total + grade;
      counter = counter + 1;
      printf( "Enter grade, -1 to end: " );
      scanf("%d", &grade);
  }
  while(grade > highest) {
   grade=highest;
   printf("High");
   scanf("%d", &highest);
  }

   average = ( float ) total / counter;
      printf( "Class average is %.2f", average );
   return(highest);
         }

Hi Nancy,

You simply want to output the highest value of the entered values?

...
highest = -1; // I assume no negative grades will be entered

while ( grade != -1 )
{
 if ( grade > highest )
  highest = grade;
 ...
}
 // I don't know for what reason you wanted another loop here which of course
 // gets never called since (grade>highest) here would evaluate to (-1>80) which is never true
 average = ( float ) total / counter;
 printf( "Class average is %.2f", average );
 return(highest);
}

further you should take care about two instances of 'highest', first global as array and second
in scope of main as int...

Also, don't use #define, use
const int HIGHEST = 90;
instead (unless this is a C question out of topic :) You get free type checking, and your debugger will be more helpful. Good luck with the course ;-)
