Must I delete the pointer before renew it

Rex_chaos · 07-15-2002, 07:52 AM

Hi all,
I have a pointer-type object

MyObject* mo = new MyObject();

If I want to recreate mo, must I delete it first like

delete mo;
mo = new MyObject();

or just renew it no matter if it's null or not?

Thanks

If you're planning to use an object pointed by mo in the future and have a method to get it somehow (list etc), you may leave it. But if mo is the only method to get to the object, delete it before creating a new one.
