Simple Program for Multiple Inheritance Using C++ Programming

To find out the student details using multiple inheritance. 

Simple Program for Multiple Inheritance Algorithm/Steps:

  • Step 1: Start the program.
  • Step 2: Declare the base class student.
  • Step 3: Declare and define the function get() to get the student details.
  • Step 4: Declare the other class sports.
  • Step 5: Declare and define the function getsm() to read the sports mark.
  • Step 6: Create the class statement derived from student and sports.
  • Step 7: Declare and define the function display() to find out the total and average.
  • Step 8: Declare the derived class object,call the functions get(),getsm() and display().
  • Step 9: Stop the program.

Simple Program for Multiple Inheritance

#include<iostream.h>
#include<conio.h>

class student {
protected:
    int rno, m1, m2;
public:

    void get() {
        cout << "Enter the Roll no :";
        cin>>rno;
        cout << "Enter the two marks   :";
        cin >> m1>>m2;
    }
};

class sports {
protected:
    int sm; // sm = Sports mark
public:

    void getsm() {
        cout << "\nEnter the sports mark :";
        cin>>sm;

    }
};

class statement : public student, public sports {
    int tot, avg;
public:

    void display() {
        tot = (m1 + m2 + sm);
        avg = tot / 3;
        cout << "\n\n\tRoll No    : " << rno << "\n\tTotal      : " << tot;
        cout << "\n\tAverage    : " << avg;
    }
};

void main() {
    clrscr();
    statement obj;
    obj.get();
    obj.getsm();
    obj.display();
    getch();
}

Sample Output

Enter the Roll no: 100

Enter two marks

90
80

Enter the Sports Mark: 90

Roll No: 100
Total    : 260
Average: 86.66
