Posts: 5,409. Grill marks have been discussed many times over the years. Sure, they are pretty and make a really strong statement about the meat, but many high-dollar restaurants reportedly draw their grill marks on with a meat-marker, while others brush on a coat of sugar water prior to it hitting the hit grill.
Pointers to member functions in C++. This is how C++ uses function pointers when dealing with member functions of classes or structs. These are invoked using an object pointer or a this call. They are type safe in that you can only call members of that class (or derivatives) using a pointer of that type.
Instead of referring to data values, a function pointer points to executable code within memory. When dereferenced, a function pointer can be used to invoke the function it points to and pass it arguments just like a normal function call. Such an invocation is also known as an indirect call, because the function is being invoked indirectly through a variable instead of directly through a fixed name or address.
