A program to illustrate multilevel inheritance. we have three classes, student, test and result. Here class student is the base class. And the class test is derived from the base class student. And the another class result is derived from the class test.

PROGRAM

#include
#include
class student
{
   		protected:
   		int rno;
   		public:
   		void getno(int);
   		void putno(void);
};
void student::getno(int a)
{
rno=a;
}
void student ::putno()
{
cout<<"rollno="<<<<"marks in sub1="<<<<"marks in sub2="<<<<"total="<<

OUTPUT
Roll number:111
Marks in sub1=75
Marks in sub2=59.5
Total=134.5
