Answer to Question #174019 in C++ for VARUN

Question

Define a class Student with the following specification:

PRIVATE DATA MEMBERS:

regno integer sname 20 character s1, s2. s3 float total float

PUBLIC MEMBER FUNCTIONS:

Student() Default constructor to initialize data members, s1 = s2 = s3 = 0

Student(rn, sn, m, p, c) Parameterized constructor accept values for regno, sname, s1, s2 and s3

calculate() Function to calculate the student total marks

putdata() Function to display all the data members of student

~student() Destructor to destroy the data objects

Answer 1

#include <iostream>
#include <string>


using namespace std;


class Student
{
public:
	Student() {};
	Student(int reg, string n, float m, float p, float c);
	float calculate();
	void putData();
	~Student() {};
private:
	int regNumber;
	string name;
	float s1;
	float s2;
	float s3;
	float total;
};


Student::Student(int reg, string n, float m, float p, float c) : regNumber(reg), name(n), s1(m), s2(p), s3(c) {}


float Student::calculate()
{
	total = s1 + s2 + s3;
	return total;
}


void Student::putData()
{
	cout << "Student number is: " << regNumber << endl;
	cout << "Student name is: " << name << endl;
	cout << "Student specification #1 is: " << s1 << endl;
	cout << "Student specification #2 is: " << s2 << endl;
	cout << "Student specification #3 is: " << s3 << endl;
	cout << "Student total is: " << calculate() << endl;
}


int main()
{
	Student Mike(10012, "Mike Wazowski", 25.3, 69.8, 95.3);
	Mike.putData();
	return 0;
