C++ Structure Initialization
...er. And dot notation is way safer if you happen to add the same type (like char*) as one of the other members above or below in the structure, because there's no risk of swapping them.

How to make my custom type to work with “range-based for loops”?
...ample of why this is useful is that your end iterator can read "check your char* to see if it points to '0'" when == with a char*. This allows a C++ range-for expression to generate optimal code when iterating over a null-terminated char* buffer.

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte ...
