Question

What do I need to implement this code. I need an ADT
//---------------------------------------------
// This would be the Student.h file
//---------------------------------------------
#include <iostream>
#include <cassert>
using namespace std;

// each student have a name, an ID (100000000~999999999), and three grades
class Student
{
    private:
    public:
      Student();
      Student();
      setName();
      setId();
      setGrade ();
      getName();
      getId();
      getGrade() ;
      printAll() ;
};
//---------------------------------------------
// This would be the Student.cpp file
//---------------------------------------------   

//====================== YOUR CODE STARTS HERE ======================


Student::Student() //default constructor
{
 
}
Student::Student(string aName, int anId, int Grade1, int Grade2, int Grade3)
//other constructor
{

 }

Student::setName()
{
   
}

Student::setId()
{
}

Student::setGrade ()
{
}
 
Student::getName()
{
    
}

Student::getId() 
{
}


// print all information of a student
Student::printAll() 
{
}

Student::getGrade() 
{

}

//====================== YOUR CODE ENDS HERE ======================


//---------------------------------------------
// This would be the main.cpp file
//---------------------------------------------
int main ()
{
   Student stu;  //calls default constructor
   string inName;
   int inId;
   int i;


   cout << "********************************"<<endl;
   cout << "View stu after default constructor" << endl;
   stu.printAll();
   cout << endl;

   //Use setters to reset the values
   cout << "Your name, please: ";
   getline(cin, inName, '\n');   // input a string
   stu.setName (inName);
   cout << "Your id, please: ";
   cin >> inId;   
 
   //====================== YOUR CODE HERE ======================
   // set stu's id and set three grades of students
   //
   //
//====================== YOUR CODE ENDS HERE ======================


   cout << endl;
   cout << "********************************"<<endl;
   cout << "View stu after setters" << endl;
   stu.printAll();
 
   cout << endl;
   cout << "********************************"<<endl;
   cout << "Testing other constructor" << endl;

   Student tom ("Tom", 99, 55, 32, 68);  //calls second constructor
   //notice using getters to print
   cout << "Hello, " << tom.getName() << endl; 
   cout << "Your Student ID is " << tom.getId() << endl;
   cout << "Your Grades are: " << endl;
   for (int i=0; i < 3; i++) 
   {
      cout << "Test " << i+1 << ": " << tom.getGrade(i) << " " << endl;
   }
}

Below is the C++ code I hope that i have provided sufficient comments for your better understanding Note that I have done proper indentation but this code is automatically left alligned on this interface

student.h

#include <iostream>
#include <cassert>
using namespace std;

// each student have a name, an ID (100000000~999999999), and three grades
class Student
{
private:
string name;
int id;
int grade[3];
public:
Student();
Student(string , int , int , int , int );
void setName(string);
void setId(int);
void setGrade (int, int ,int);
string getName();
int getId();
int getGrade(int) ;
void printAll() ;
};

student.cpp

#include "student.h"
Student::Student() //default constructor
{
//initializing with null or empty values
name="";
id=0;
for(int i=0;i<3;i++)
grade[i]=0;
}
Student::Student(string aName, int anId, int Grade1, int Grade2, int Grade3)
//other constructor
{
//set all the parameters
name = aName;
id = anId;
grade[0] = Grade1;
grade[1] = Grade2;
grade[2] = Grade3;
}

void Student::setName(string aName)
{
name = aName;
}

void Student::setId(int anId)
{
id = anId;
}

void Student::setGrade (int Grade1, int Grade2, int Grade3)
{
grade[0] = Grade1;
grade[1] = Grade2;
grade[2] = Grade3;
}

string Student::getName()
{
return name;
}

int Student::getId()
{
return id;
}

// print all information of a student
void Student::printAll()
{
cout<<"Name: "<<name<<endl;
cout<<"Id: "<<id<<endl;
cout<<"Grades: ";
for(int i=0;i<3;i++)
cout<<grade[i]<<" ";
cout<<endl;
}

int Student::getGrade(int i)
{
return grade[i];
}

main.cpp

#include "student.cpp"
int main ()
{
Student stu; //calls default constructor
string inName;
int inId;
int i;

cout << "********************************"<<endl;
cout << "View stu after default constructor" << endl;
stu.printAll();
cout << endl;

//Use setters to reset the values
cout << "Your name, please: ";
getline(cin, inName, '\n'); // input a string
stu.setName (inName);
cout << "Your id, please: ";
cin >> inId;

stu.setId(inId);

int Grade1, Grade2, Grade3;
cout << "Your grades, please: ";
cin >> Grade1 >> Grade2 >> Grade3;
stu.setGrade(Grade1, Grade2, Grade3);

cout << endl;
cout << "********************************"<<endl;
cout << "View stu after setters" << endl;
stu.printAll();

cout << endl;
cout << "********************************"<<endl;
cout << "Testing other constructor" << endl;

Student tom ("Tom", 99, 55, 32, 68); //calls second constructor
//notice using getters to print
cout << "Hello, " << tom.getName() << endl;
cout << "Your Student ID is " << tom.getId() << endl;
cout << "Your Grades are: " << endl;
for (int i=0; i < 3; i++)
{
cout << "Test " << i+1 << ": " << tom.getGrade(i) << " " << endl;
}
}

Below is the screenshot of output

I have tried to explain it in very simple language and I hope that i have answered your question satisfactorily.Leave doubts in comment section if any.
