c++: when to use pointers?

Question

After reading some tutorials I came to the conclusion that one should always use pointers for objects. But I have also seen a few exceptions while reading some QT tutorials

Answer 1

Pass by value with well behaved copyable objects is the way to go for a large amount of your code.

If speed really matters, use pass by reference where you can, and finally use pointers.

Answer 2

Use pointers when you don't want your object to be destroyed when the stack frame is emptied.

Use references for passing parameters where possible.
