C++ program using single Inheritance

June 18, 2016

Aim:

To write a program to implement Inheritance

Algorithm:

Step 1: Start

Step 2: Declare the base class student.

Step 3: Declare and define the function getdata() to get the student details.

Step 4: Declare the derived class marks.

Step 5: Declare and define the function getm() to get the marks of the student.

Step 6: Define the function display() to calculate total marks and print the student details.

Step 7: Create an object std for derived class marks.

Step 8: Call the function getdata() to read the student details.

Step 9: Call the function getm() to read the student’s marks.

Step 10:  Call the function display() to print the student details and total marks.

Program Code: 

#include<iostream.h>

#include<conio.h>

class student

{

public:

int rno;

char name[20];

void getdata()

{

cout<<"Enter rollno : ";

cin>>rno;

cout<<"Enter name : ");

cin>>name;

}

};

class marks:public student

{

int m1,m2,m3,tot;

public:

void getm(){

cout<<"Enter 3 Marks :";

cin>>m1>>m2>>m3;

}

void display()

{

cout<<"---Student Details---\n";

cout<<"Roll Number : "<<mo<<"\n"<<"Name : "<<name<<"\n"<<"Total Marks : "<<m1+m2+m3<<"\n";

}

};

void main()

{

marks std;

clrscr();

std.getdata();

std.getm();

std.display();

getch();

}

Output:

Enter rollno: 1

Enter Name: Adeeb

Enter 3 Marks: 70 75 68

—Student Details- – –

Roll Number : 1

Name : Adeeb

Total Marks : 213
