Am learning CPP and in the below code snippet, I am expecting 40 as the answer, but getting 30. Can anyone please help to identify what am I doing wrong.
The program may not make sense, but its just for learning.
class Shape {
protected:
int shape = 10;
public:
int get() {
return shape;
}
virtual void process() {
shape = 30;
}
};
class Rectangle : public Shape {
public:
void process() {
shape = 40;
}
};
class Object : Shape {
Shape m_sh;
public:
Object(Shape &sh) {
m_sh = sh;
m_sh.process();
}
int getShape() {
return m_sh.get();
}
};
int main(int argc, char *argv[]) {
Rectangle rect;
Object obj1 = Object(rect);
std::cout << obj1.getShape() << std::endl; // am expecting 40, but getting 30.
}
