C++ Multilevel Inheritance
Multilevel inheritance is such an inheritance in which a derived class is created from another derived class.
C++ Multilevel Inheritance Example
In this example, a base class Student is inherited in a derive class Marks, and the derived class Marks is further inherited in another derive class Total.
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 | #include <iostream> using namespace std; class Student{ protected: int rollno; public: void getnum(int a){ rollno = a; } void putnum(){ cout << "Roll Number Is: "<< rollno << "\n"; } }; class Marks : public Student{ protected: int sub1; int sub2; public: void getmarks(int x,int y){ sub1 = x; sub2 = y; } void putmarks(void){ cout << "Subject 1: " << sub1 << "\n"; cout << "Subject 2: " << sub2 << "\n"; } }; class Result : public Marks{ protected: float tot; public: void disp(void){ tot = sub1+sub2; putnum(); putmarks(); cout << "Total: "<< tot; } }; int main(){ Result res; res.getnum(5); res.getmarks(70,60); res.disp(); return 0; } |
Output:
0 1 2 3 4 5 | Roll Number Is: 5 Subject 1: 70 Subject 2: 60 Total: 130 |
