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.
The void function accomplishes its task and then returns control to the caller. The void function call is a stand-alone statement. For example, a function that prints a message doesn't return a value. The code in C++ takes the form: void printmessage ( ) {. cout << I'm a function that prints a message!;
