[Failure]

Write your question here.

  
// determine average grade for test
double GradeBook::getAverageGrade()
{
   int total = 0; // initialize total

   // sum grades in array
   for ( int grade = 0; grade < STUDENTS; grade++ )
      total += grades[ grade ];

   // return average of grades
   return static_cast< double >( total ) / STUDENTS;
} // end function getAverage

// find maximum grade
int GradeBook::getMaximum()
{
   int highGrade = 0; // assume highest grade is 0

   // loop through grades array
   for ( int grade = 0; grade < STUDENTS; grade++ )
   {
      // if current grade higher than highGrade, assign it to highGrade
      if ( grades[ grade ] > highGrade )
         highGrade = grades[ grade ]; // new highest grade
   } // end for

   return highGrade; // return highest grade
}

GradeBook.cpp: In member function ‘double GradeBook::getAverageGrade()’:
GradeBook.cpp:205: error: invalid conversion from ‘int*’ to ‘int’
GradeBook.cpp: In member function ‘int GradeBook::getMaximum()’:

Anyone can help me with this error?

[jonnin]

what is students?

[Failure]

A constant int
jonnin

[jonnin]

the compiler thinks something in there is a pointer.
is grades a ** or reference to *?

[Failure]

array of int pointers int grades[STUDENTS][TESTS];

[jonnin]

that is it then.
you cant compare it that way...

if ( grades[ grade ] > highGrade )

should be grades[?][?] > highGrade

but I don't know what your indices mean.
You are comparing an int* to an int, just like it said.

Huh that worked! Thanks!
