Memory Management part I

• This is chapter 7.
• Read up to 234, Smart pointers.
  • We will deal with raw pointers first.
  • We will come back later and deal with smart pointers.
• As a c++ programmer, people will expect you to know about pointers.
  • And dynamic memory.
• you probably encountered this at the end of 230
  • But you need a refresher.
  • Or to even go over it again.
• Read the second and third paragraphs on page 211
• What is dynamic memory?
  • Why is this type of memory needed?
  • Where have you seen it in use?
• What is the stack?
• What is the heap?
• What do the operators new and delete do?
• How is this different from new[] and delete[]?
• What is NULL, nullptr?
• What does this do int * x;
• What does this do x = &y;
• What does this do *x = 99;
• What does this do cout << *x;
• Take a look at array.cpp.
• What is a shallow copy and a deep copy?
