The type of file is irrelevant if you're treating it as a sequence of bytes. As long as you don't lose any packets in the transfer, the .exe will be reconstructed correctly and will run on a matching OS.

If you have to delete an entry, the simplest method conceptually is to rewrite the file in its entirety without the entry in question. For huge files that can be a performance issue, but for a school project you don't need to concern yourself with huge files.

Without looking at your code (because let's be fair, there's a lot of it), my gut reaction is that you've done something somewhere that corrupted the vector. This is most likely due to an out of range access or wayward pointer. So in troubleshooting I'd focus on memory corruption. Can …

`sizefn_t` is a [typedef](http://publib.boulder.ibm.com/infocenter/macxhelp/v6v81/index.jsp?topic=%2Fcom.ibm.vacpp6m.doc%2Flanguage%2Fref%2Fclrc03typdef.htm) for a [pointer to a function](http://publib.boulder.ibm.com/infocenter/comphelp/v7v91/index.jsp?topic=%2Fcom.ibm.vacpp7a.doc%2Flanguage%2Fref%2Fclrc07cplr242.htm). The typedef simplifies the syntax for said pointers because otherwise the syntax is pretty awkward: // Declare a pointer to function and point it to useSizeFace() double (*sizefn)(double*) = userSizeFace; All the typedef does is wrap the awkwardness into a …

Not to mention it wouldn't pass code review in any development house I've worked with (assuming it compiled). The code itself is brittle and the solution is clearly written by someone who hasn't done much date and time programming.

I'd suggest reading each line with fgets() and then parsing it in memory to extract fields. You can do the parsing with sscanf(), though it can get a little tricky unless you guarantee that the file ends with a newline character, because you need to consider fields that end in …

When you forward declare a class, you only tell the compiler that it exists, not what's in it. So while the declarations are fine, the definition of FileTwo::Test() would need to be deferred until after both classes have been introduced completely: class FileOne; class FileTwo { public: int Test(FileOne One); …

GCC doesn't support void main, therefore any use of it invokes undefined behavior. More specifically, if the compiler doesn't support void main then the code it produces could be [very wrong or dangerous](http://users.aber.ac.uk/auj/voidmain.cgi).

An example is mentioned specifically in the form of prepending size information to the block of memory. If the object is small, the overhead of size information can be prohibitive. It's only when the allocated objects get bigger that the "bookkeeping" information gets amortized away.
