Episode Thirteen: The Ways Of sizeof

C++ inherits from C the sizeof operator; it yields the number of bytes in the object representation of its operand. It comes in two flavours, `sizeof( type-name )` and `sizeof expression`. It's important to note that expressions in the form `sizeof( ptr )->member` refer to the second sizeof form, and are not a syntactic error.

While sizeof is just about getting the size of its operand, its power extends beyond that.
