When a member function is invoked on a particular object, that object is known as the receiver. Within the body of the member function, you can access the member variables of the receiver using the "this" pointer. In this course, discover how the this pointer works and practice using it to access states. Next, learn about constness in object-oriented programming and the restrictions for what such methods can do. Finally, learn how to use the mutable keyword to mitigate constness. After completion of the course, you'll be able to access member variables from within member functions, create const and non-const objects and functions, and use the mutable specification to identify states that can be changed without changing the meaning of the object.

  • use const pointers and const references
    create const and non-const objects and functions
    modify returned values of functions to modify the state
    create setters, disable const using const_cast, and use mutable keywords
    summarize the key concepts covered in this course
