*this vs this in C++

This is a pointer, and *this is a pointer that has been dereferenced. If you had a function that returned this, it would be a pointer to the current object, but a function that returned *this would be a "clone" of the current object, created on the stack unless you defined the method's return type to be a reference. A small application that demonstrates the difference between working with copies and working with references: #include <iostream> class Foo { public: ...READ MORE
