Hybrid inheritance is the combined form of all the rest of the inheritances (Single, Multiple,Multilevel and Hierarchical).

Sample Program
   #include <iostream.h>
   class mm
   {
       protected:
       int rollno;
       public:
        void get_num(int a)
        {
          rollno = a;
       }
       void put_num()
      {
           cout << "Roll Number Is:"<< rollno << "\n";
      }
   };
   class marks : public mm
   {
        protected:
        int sub1;
      int sub2;
        public:
        void get_marks(int x,int y)
        {
          sub1 = x;
          sub2 = y;
        }
        void put_marks(void)
        {
           cout << "Subject 1:" << sub1 << "\n";
           cout << "Subject 2:" << sub2 << "\n";
       }
   };

   class extra
   {
       protected:
      float e;
       public:
       void get_extra(float s)
       {
           e=s;
       }
       void put_extra(void)
       {
           cout << "Extra Score::" << e << "\n";
       }
   };

   class res : public marks, public extra
   {
        protected:
        float tot;
        public:
        void disp(void)
      {
          tot = sub1+sub2+e;
          put_num();
          put_marks();
           put_extra();
           cout << "Total:"<< tot;
      }
    };

   int main()
    {
       res std1;
       std1.get_num(10);
        std1.get_marks(10,20);
       std1.get_extra(33.12);
        std1.disp();
       return 0;
    }

Output:
Roll Number Is: 10
Subject 1: 10
Subject 2: 20
Extra score:33.12
Total: 63.12
