I scored 2, but mostly out of luck for being 100% sure only about the 1st question, as I encountered alignment problems a lot of times in the past when dealing with structures to be sent through the network, and also between different architectures (and sometimes endianess too). If memory serves, there are #pragma directives to force the compiler to align structure members to a given interval, but they're compiler dependent and would make a non portable piece of code even less portable.
