Subclass destructor, how to call the superclass destructor?

 
The class Parent 
{
To the Parent () {} 
} 

Child: class public Parent 
{
~ the Child () {} 
} 

Child () that can be invoked to ~ ~ the Parent ()

CodePudding user response:

I tried to let both the destructor is virtual functions, but still not transferred to, feeling is also a demon

CodePudding user response:

As virtual automatically calls,

CodePudding user response:

Don't write any code automatically calls,

CodePudding user response:

don't have to write any code automatically calls,

Don't write the virtual words, calling sequence is not correct. That is to say, does not automatically call
For example the following code

 # include & lt; Iostream> 
using namespace std; 

The class Base {
Public: 
~ Base () {
Cout & lt; <"Base destory" & lt; } 
}; 
Child: class public Base {
Public: 
~ the Child () {
Cout & lt; <"The Child destory" & lt; } 
}; 
Int main (void) 
{
The Base * b=new Child; 
The delete b; 
}
