be public, and all the fuctions are pure virtual functions.

Here is the example code

#define interface struct

interface <inter face name >
{
virtual int add(int x, int y) =0;
};

class A : public <<inter face name>>
{
public:
.
.

int add (int x, int y);
};

int A:: add(int x, int y)
{
return x+y;
}
