Use variable form chils class

[vbourbeau]

Hi,
I'm new in c++. I want to use a public variable form the parent class but I'v got always the error
Expression must be a modifiable value

class Shapes
{
private:	
public:
	float center[2];
	virtual void draw() const = 0; 

};

class Rect : public Shapes
{
private:
public:
	void draw() const override;
};


void Rect::draw() const
{
center[0] = 1; // Expression must be a modifiable value
}

Remove the const on your member functions.
