C++ program using single Inheritance
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
