#include <typeinfo>

class Shape{
public:
virtual ~Shape()=0;
};

class Circle : public Shape{};
class Square : public Shape{};

void function(const Shape * s)
{
if (typeid(*s)==typeid(Circle))
{
//do something for Circle
}
else if (typeid(*s)==typeid(Square))
{
//do something for Square
}
}

솔루션

고유 식별자를 리턴하는 virtual classOf() 함수를 사용하여 클래스를 구현하거나 동적 캐스트의 성공을 테스트하십시오.

class Shape{
public:
virtual ~Shape()=0;
};

class Circle : public Shape{};
class Square : public Shape{};

void function(const Shape * s)
{
Shape *sh = const_cast<Shape*> (s);

if (dynamic_cast<Circle *>(sh) )
{
//do something for Circle
}
else if (dynamic_cast<Square *>(sh) )
{
//do something for Square
}
}
