Hi,
I'm not sure if
return *this
is the only way we could return an instance of a class who called a member function? Reason why I asked is because our instructor told us to avoid using pointers if necessary and I'm wondering if this is a case where the only necessary way to do it is by returning the this pointer.
I'm working wit...

class Foo {
public:
Foo(char x);
Foo(char x, int y);
~Foo();
void abc();
void dev();
};
void Foo::dev()
{
printf("inside dev \n");
}
void Foo::abc()
{
printf("inside abc \n");
delete this;

context 1: class D : public B1, public B2{};
context 2: B2 takes B1 to initialize: B2( B1 * ) //B2's constructor
my question is in D's initialization list:
D::D() : B1(), B2( ? )... What should be in ?
I don't want to put " (B1*)this " in the ? place, because it's no good to use "this" in initialization list. And since B1 part ha...
Is there a way to force the this keyword to act as a ref argument? I would like to pass in a visitor that modifies multiple properties on the object, but this only wants to act like a value parameter.
Code in Object:
public void Accept(Visitor<MyObject> visitor)
{
visitor.Visit(this);
}
Code in Visitor:
public void Visit(ref Vis...
Summary:
I want to know if it is possible to do something like this:
{a: 'A',b: this.a}
...by using some other pointer like {a: 'A',b: self.a} or {a: 'A',b: own.a} or anything else...

<select name="selectbox" onchange="alert(this.text)>

I was shocked just a moment ago to discover that the following is legal (the C# equivalent is definitely not):
Class Assigner
''// Ignore this for now.
Public Field As Integer
''// This part is not so weird... take another instance ByRef,
''// assign it to a different instance -- stupid but whatever. '
Sub Assign(By...
