What is Class and Objects in C++?

  • Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
  • The variables inside class definition are called as data members and the functions are called member functions.
  • Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.
  • Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
  • Each object has different data variables. Objects are initialized using special class functions called Constructors.

Below is the source code for C++ Program to enter student details using Virtual Class which is successfully compiled and run on Windows System to produce desired output as shown below :

 
 

SOURCE CODE : :

/*  C++ Program to enter student details using Virtual Class  */

#include<iostream>

using namespace std;

class student

{
    protected:

        int roll_no;

    public:

        void get_no(int x)
        {
            roll_no=x;
        }

        void put_no()
        {
            cout<<"\nRoll Number :: "<<roll_no<<"\n";

        }
};

class test: virtual public student
{
    protected:
        float sub_marks;

    public:
        void get_submarks(float y)
        {
            sub_marks=y;
        }

        void put_submarks()
        {
            cout<<"\nSubject Marks :: "<<sub_marks<<"\n";
        }
};




class sports: public virtual student
{
    protected:
        float sp_marks;

    public:
        void get_spmarks(float z)
        {
            sp_marks=z;
        }

        void put_spmarks()
        {
            cout<<"\nSports Marks :: "<<sp_marks<<"\n";
        }

};

class result: public test, public sports
{

    float total_marks;

    public:
        void put_result()
        {
            total_marks=sub_marks+sp_marks;
            put_no();

            put_submarks();
            put_spmarks();
            cout<<"\nTotal Marks :: "<<total_marks<<"\n";
        }
};


int main()
{
    result R;
    R.get_no(34);
    R.get_submarks(67.2);
    R.get_spmarks(98.9);
    R.put_result();

    return 0;
}

OUTPUT : :

/*  C++ Program to enter student details using Virtual Class  */

Roll Number :: 34

Subject Marks :: 67.2

Sports Marks :: 98.9

Total Marks :: 166.1

Process returned 0

Above is the source code and output for C++ Program to enter student details using Virtual Class which is successfully compiled and run on Windows System to produce desired output.
