Answer to Question #213018 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:
	int rollno;
	string name;
public:
	void setData(int rn,string n){
		rollno = rn;
		name = n;
	}
};


class Fees: public Student
{
protected:
	int fees;
public:
	void submitFees(int f){ 
		fees = f;
	}
	void generateReceipt()
	{
		cout<<"Fee Receipt:";
		cout<<"Roll No: "<<rollno<<"\n";
		cout<<"Name: "<<name<<"\n";
		cout<<"Fee: "<<fees<<"\n";
	}
};


class Result: public Fees
{
private:
	int tests;
	int activities;
	int sports;
public:
	void setMarks(int tests, int activities, int sports)
	{ 
		this->tests=tests;
		this->activities = activities;
		this->sports = sports;


	}
	void generateReceipt(void)
	{
		float tm = tests + activities + sports;
		float average=tm/3.0;
		char grade;
		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';
		}
		Fees::generateReceipt();
		cout<<"\n\nMarks Receipt:";
		cout<<"Marks in Tests: "<<tests<<"\n";
		cout<<"Marks in Activities: "<<activities<<"\n";
		cout<<"Marks in Sports: "<<sports<<"\n";
		cout<<"Grade: "<<grade<<"\n\n";
	}
};
int main(void)
{
	Result studentSmith;
	studentSmith.setData(89656645,"Peter Smith");
	studentSmith.submitFees(85);
	studentSmith.setMarks(75,65,85);
	studentSmith.generateReceipt();
