| Hola profesor, | |
| Me ha surgido una duda con una pregunta: supongamos que la clase B hereda de A un método tutu que usa la constante C definida en A. Si en la clase B se define C, ¿qué definición de C usará tutu, la de A o la de B? | |
| Un saludo. | |
| =end | |
| class A | |
| C = 4 | |
| def tutu | |
| puts C |
