Answer to Question #213778 in C++ for Hemambar

Question

Define a class Student with data members as rollno and name. Derive a class Fees from student

that has a data member fees and functions to submit fees and generate receipt. Derive another class

Result from Student that displays the marks and grade obtained by the student. Write a program that

extends the class Result so that the final result of the Student is evaluated based on the marks obtained

in tests, activities and sports.

Answer 1

#include <iostream>
#include <string>


using namespace std;




class Student
{
protected:
	string rollno;
	string name;
public:
	void setData(string rollno,string name){
		this->rollno = rollno;
		this->name = name;
	}
};


class Fees: public Student
{
protected:
	int fees;
public:
	void submitFees(int fees){ 
		this->fees = fees;
	}
	void generateReceipt()
	{
		cout<<"Fee Receipt:";
		cout<<"\nRoll No.: "<<this->rollno;
		cout<<"\nName: "<<this->name;
		cout<<"\nFee: "<<this->fees;
	}
};


class Result: public Fees
{
private:
	int tests;
	int activities;
	int sports;
	int totalMarks;
	string grade;
public:
	void setMarks(int tests, int activities, int sports)
	{ 
		this->tests=tests;
		this->activities = activities;
		this->sports = sports;
		this->totalMarks = tests + activities + sports;
		float average=this->totalMarks/3.0;
		if(average>=90)
		{
			grade = "A";
		}
		else if(average>=80 && average<90)
		{
			grade = "B";
		}
		else if(average>=70 && average<80)
		{
			grade = "C";
		}
		else if(average>=60 && average<70)
		{
			grade = "D";
		}
		else{
			grade = "F";
		}
	}
	void generateReceipt(void)
	{


		Fees::generateReceipt();
		cout<<"\n\nMarks Receipt:";
		cout<<"\nMarks in Tests: "<<tests;
		cout<<"\nMarks in Activities: "<<activities;
		cout<<"\nMarks in Sports: "<<sports;
		cout<<"\nTotal Marks: "<<totalMarks;
		cout<<"\nFinal Grade: "<<grade;
	}




};
int main(void)
{
	Result student;
	student.setData("7855554","Mary Clark");
	student.submitFees(80);
	student.setMarks(80,70,90);
	student.generateReceipt();


	cout<<"\n\n\n";






	system("pause");
	return 0;
