Question

anyone help me seperate this into a header file (.h contains function and variable delcaration) and a implementation file (.cpp that contains the definitions for the functions and variables)

#include <iostream>
using namespace std;

#define MAXSIZE 100

class Grader{
private:
int my_Values[MAXSIZE];
int my_valuesSeenSoFar;
public:
Grader(){
my_valuesSeenSoFar = 0;
}
void addScore(int score){
my_Values[my_valuesSeenSoFar++] = score;
}
void addScores(int scores[], int size){
for(int i = 0; i < size; i++){
my_Values[my_valuesSeenSoFar++] = scores[i];
}
}
void clear(){
for(int i = 0; i < my_valuesSeenSoFar; i++) my_Values[i] = 0;
my_valuesSeenSoFar = 0;
}
int findBiggest() const{
int biggest = my_Values[0];
for(int i = 1; i < my_valuesSeenSoFar; i++){
if(my_Values[i] > biggest) biggest = my_Values[i];
}
return biggest;
}
int findSmallest() const{
int smallest = my_Values[0];
for(int i = 1; i < my_valuesSeenSoFar; i++){
if(my_Values[i] < smallest) smallest = my_Values[i];
}
return smallest;
}
};

int main(){
Grader g;
int d[5]= {99,70,85,93,84};
int 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
}

//Grader.h

#include <iostream>

using namespace std;

#define MAXSIZE 100

class Grader{

private:

int my_Values[MAXSIZE];

int my_valuesSeenSoFar;

public:

Grader();

void addScore(int score);

void addScores(int scores[], int size);

void clear();

int findBiggest()const;

int findSmallest()const;

};

-------------------------------------------

//Grader.cpp

#include"Grader.h"

Grader::Grader(){

my_valuesSeenSoFar = 0;

}

void Grader::addScore(int score){

my_Values[my_valuesSeenSoFar++] = score;

}

void Grader::addScores(int scores[], int size){

for(int i = 0; i < size; i++){

my_Values[my_valuesSeenSoFar++] = scores[i];

}

}

void Grader::clear(){

for(int i = 0; i < my_valuesSeenSoFar; i++) my_Values[i] = 0;

my_valuesSeenSoFar = 0;

}

int Grader::findBiggest() const{

int biggest = my_Values[0];

for(int i = 1; i < my_valuesSeenSoFar; i++){

if(my_Values[i] > biggest) biggest = my_Values[i];

}

return biggest;

}

int Grader::findSmallest() const{

int smallest = my_Values[0];

for(int i = 1; i < my_valuesSeenSoFar; i++){

if(my_Values[i] < smallest) smallest = my_Values[i];

}

return smallest;

}

--------------------------------------------

//main.cpp remains same, except including Grader.h header file,, still posting main.cpp and output

#include <iostream>

#include"Grader.h"

using namespace std;

int main(){

Grader g;

int d[5]= {99,70,85,93,84};

int 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

}

---------------------------------------------

//output

Best Score = 99
Worst Score = 70
Best Score = 100
Worst Score = 50
