• Surindra circular reference in parent/child classes

  I have been trying to understand some code that another guy wrote, and though his code compiles and runs, it seems like it should never have compiled. He has 2 classes. One class is basically the parent, and it includes a pointer to the child it creates. As the child is being created, the parent passes the constructor a "this" pointer, so the child can later access variables in the parent. When I try to duplicate this logic, ...Show All
