CodePudding user response：

You can make the function parameter to be a reference or a pointer to the base class as shown below.

void eat(const Fruit* f)
{
    //code here
}

Or

void eat(const Fruit& f)
{
   //code here
}

You can remove the low-level const if you want to be able to make changes through f.
