static const double in c++
- by Crystal
Is this the proper way to use a static const variable? In my top level class (Shape)
#ifndef SHAPE_H
#define SHAPE_H
class Shape
{
public:
static const double pi;
private:
double originX;
double originY;
};
const double Shape::pi = 3.14159265;
#endif
And then later in a class that extends Shape, I use Shape::pi. I get a linker error. I moved the const double Shape::pi = 3.14... to the Shape.cpp file and my program then compiles. Why does that happen? thanks.
