1. Advanced memory management

2. Problems with memory
management
• Unexpected returns
• Exceptions
• Should we delete created pointer?

3. Smart pointers
• Pointer holder
• Smart pointer

4. Standard smart pointers
• unique_ptr
• shared_ptr
• weak_ptr
• auto_ptr (deprecated, do not use it)

5. Few simple rules
• Avoid using raw-pointers
• Use reference if user shouldn’t save passed
object
• Use unique_ptr if your object is the only user
of given object
• Use shared_ptr if your object should share
given object

6. More rules
• Each object should have only one owner
• Owner should share resources only with it’s
children, not with parent
• Use vector instead of dynamically allocated
arrays
