Interface

 


#include<iostream>;
using namespace std;


class ABC {

  public:
  virtual void SUB() = 0;
  virtual void SUB() = 0;
};

//interface and abstract method are same but one small changes
// abstract class              VS         interface
//cannot create object      same

//in abstract cls at list 1                only virtual fun interface class 
//virtual function                         define prototype or blue print of function
//virtual function define 
//data member (int a;)and
//member function


class XYZ :public ABC {

public:
void SUB() override {

}
};





int main() {
  //ABC obj;
  //B obj;
  // a=10 b=20,c=30;



  return 0;
}
