When to use “delete”?

Question

I want to store 10 Obj object in objList, but i don\'t know when is appropriate use delete in this case. If i use delete Obj;

Answer 1

Yes, you should.

There should be a corresponding delete for every new in your program.

But your program doesn't need dynamic allocation:

Obj obj;
obj.u = i;
obj.v = i + 1;
objList.push_back(obj);

Also, your syntax was wrong - objList.push_back(*Obj); // should be *obj, not *Obj
