Deriving only one class from base class is called single inheritance.
For example:
#include<iostream.h>
#include<conio.h>
class student
{
public:
int rno;
char na[30];
void input();
};
void student::input()
{
cout<<"enter the student name";
cin>>na;
cout<<"enter the register no:";
cin>>rno;
}
class mark:public student //derivation
{
int m1,m2,m3;
float t,av;
public:
void display()
{
cout<<"Enter m1,m2,m3 values\n"
cin>>m1>>m2>>m3;
t=m1+m2+m3;
av=t/3;
cout<<endl<<"name="<<na;
cout<<endl<<"Register number="<<rno;
cout<<endl<<"total="<<t;
cout<<endl<<"average="<<av;
}
};
void main()
{
clrscr();
mark ob;
ob.input();
ob.display();
getch();
}
