Self Assignment Why do we need to protect against the self assignment when we do overloading assignment operator? But before we dig into the reason why, who would do that kind of silly self assignment? Window w; w = w; // nobody will do this w[i] = w[j]; // this may happen ...

I need to implement an assignment operator that is overloaded to assign the contents of one array to another. Here's what I have so far (the class is called ArrayB): ArrayB & operator= (const ArrayB & other) { if (this != &other) { //Logic goes here to assign arrays } ...
