Grader Class - best and worst scores

Rezivor123 (25)
Hi,
I am new to array and classes,
I am working on a homework assignment and have come to a bit of a stand still

We are to add scores through an addScore object and then have the program sort the biggest and smallest scores. MAX_SIZE constant is to be 100. The professor gave us the numbers to put in our arrays and what number we should get once the arrays have been passed through the find biggest and smallest functions

I was able to find some examples in the book and build a good start of the coding for the grader.h and grader driver.cpp

but I am having trouble figuring out what to program into the grader.cpp-- specifically where to start with the addScores objects


below is the code I have so far

grader.h

Grader( );

void addScore( int score );
void addScores( int scores[], 
                int size );
void clear(); 

int findBiggest( ) const;
int findSmallest( ) const;
int my_Values[ MAXSIZE ];
int my_valuesSeenSoFar;

#include <iostream.h>
#include <stdlib.h>

#include "grade.h"

Grader g;
double d[5]= {99,70,85,93,84};
double e[4]= {100,81,60,91};

g.addScore( 75 );
g.addScore( 82);
g.addScores( d, 5 ); 

cout << "Best Score = " << g.findBiggest( ) << endl;
/// should give value 99
cout << "Worst Score = " << g.findSmallest( ) << endl;
/// should give value 70
g.clear( );

g.addScore( 50 );
g.addScore( 74 );
g.addScores( e, 4 ); 

cout << "Best Score = " << g.findBiggest( ) << endl;
/// should give value 100
cout << "Worst Score = " << g.findSmallest( ) << endl;
/// should give value 50


I could use some help with programing the grader.cpp file.

Thank you

Best,

In the first snippet it looks like you wanted to write a class def, but you didn't write it out correctly.

In the second snippet you write expressions outside of a function, this is not allowed in C++. You must write that code (except for the #includes, probably) inside a function, such as main.

Hi,
Thank you for that
I was able to sketch out a grader.cpp

so far the full code is as such

g.addScore( 75 );
g.addScore( 82);

cout << "Best Score = " << g.findBiggest( ) << endl;
/// should give value 100
cout << "Worst Score = " << g.findSmallest( ) << endl;
/// should give value 50 
}


I'm still trying to figure out how to build the AddScores functions, to add numbers to the array

and I am a little confused on how to obtain findSmallest

thank you

Grader.h still fails to correctly define a class.
