    Hi I was just wondering if I create a pointer using the new operator and then I call the new operator on that same pointer later on would that overwrite the existing pointer so that I do not waste memory on the heap or do I have to delete it then use the new operator again.

    EG:

    Code:
     
    ClassA* objA = new ClassA();
    .
    .
    objA = new ClassA();
     
    OR

    Code:
     
    ClassA* objA = new ClassA();
    .
    .
    delete objA;
    objA = new ClassA();
     

    Thank You in advance
