potential dangers of merging two files of unknown size?
Hello all. I have a binary file that I need to insert a header at the beginning of.

How are structs laid out in memory in C++?
Is the way C++ structs are laid out set by the standard, or at least common across compilers? I have a struct where one of its members needs to be aligned on 16 byte boundaries, and this would be easier if I can guarantee the ordering of the fields. Also, for non-virtual classes, is the address of the first element also likely to be th...
