If you want to modify the information of the corresponding derived class object at runtime when using general programming (that is, polymorphism), we can use the powerful runtime type information mechanism in C ++, to change the object state of the

We can open a one-dimensional array w []. The subscript of the array is the endpoint value of the range. cow is at the beginning of w [s. When we encounter an interval, we can see how many values will be covered in this interval (actually the number

Please specify the source for reprinting. Thank you! When using the reference type to pass the returned value, it is often seen that its advantage is very obvious. If the object is referenced, this can reduce the number of operations such as object
