why is delete an expression and not a statement? (in my draft copy of
the standard).
I was about to ask the same question about "throw" but found an
expression case of throw("return boolvalue ? 5 : throw 5;").
but "delete" neither does exit the scope nor has a return value.
any idea?
thanks,

Hi,
We all know the below codes are dangerous:
{
int *p = new int;
delete p;
delete p;
}
And we also know the compilers do not delete p if p==NULL.
So why compilers do not "p = NULL" automatically after programs do "delete p"?

This problem shows up in Firefox 1.5.0.1 and Rhino 1.6R2.
I've found that if I have an XML node expression that ends in a filter,
I can't use it with the delete operator. In the following example, the
delete operation has no effect:
var z = <abc><foo a='1'>1</foo><foo a='2'>2</foo></abc>;
alert(z.foo.(@a == '2'));
delete z.foo.(@a == '2');

I have a DataGrid control with a LinkButton command column that deletes the
row. What I want to do is set it up so that there's a client-side Confirm
alert BEFORE the actual Delete command gets called on the server-side. That's
easy to do with normal buttons, etc. as follows...
<asp:Button ID="ConfirmBtn" Text="ConfimMe!"
OnClientClick="if(!confirm('Are you sure?'))return false;"
OnClick="ConfirmBtnClickHandler" Runat="server" />

Hi everyone,
Im just starting out with C++, and am curious to know how "delete
<pointer>", knows about the number of memory locations to free.
I read somewhere that delete frees up space assigned to <pointerby
"new". Does "new" create a list of pointer names and the size of the
memory array they point to? I also read that some compilers may store
the number of consec mem locations a pointer points to, just before the
first data...

i see serveral source codes , and i found they almost only use "new"
and "delete" keywords to make they object.
Why should i do that , and as i know the object is going to be destroy
by itself at the end of the app
for example:
class test
{
public:
int x;

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
