你能解释一下这个神秘的代码吗？

Question

Found this while debugging C++ code in Embarcadero RAD Studio. It appears to compile, but frankly, while it seems obvious what it's meant to do, I can't figure out what it's actually doing.

TObject *objPtr ( new TObject() );

If anyone could offer a sane explanation, I would be grateful.

Answer 1

It's using direct initialization syntax to initialize objPtr to a newly allocated Tobject. For most practical purposes, it's equivalent to Tobject *objPtr = new Tobject(); .

Answer 2

This creates an object of type TObject on the heap and stores its location in a TObject pointer called objPtr. It should be deleted via the line delete objPtr at some point to prevent memory leaks.
