Why can I do this:
return (tarea->ini == NULL) && (tarea->fin == NULL); // no hay parentesis global
but not
while (tarea->ini != NULL) && (tarea->ini != kol) // no hay parentesis global
?
since it tells me that I should put the while like this:
while ((tarea->ini != NULL) && (tarea->ini != kol)) // parentesis global
I want to know why it is not going to be something that that return is verifying only the first condition...
