Assume:

class Foo {

 Foo() { /*stuff*/}
 ~Foo() { /* stuff*/}

//stuff

};

main() {
 
 Foo** fooArray = nil;
 fooArray = new Foo*[100];

// do something

}

My question has to do with deallocating fooArray. If I am not concerned with
deleting the contents of fooArray (the 100 Foos), it seems like:

delete fooArray;

is correct. If I did  want to delete the 100 Foos, would this be correct:

delete [100]fooArray;

or would I have to:

  for (int i = 0; i < 100; i++) {
    delete fooArray[i];
  }
  delete fooArray;

Would the answer be different if Foo does not have a
constructor and destructor? 

thanks.
