the file is also not compatible between architecture to the next! :( i.e. endianess for sure.. but probably computer struct paddings too! :/ though haven't used C in decades, so I am not so sure about that one...

Sometimes that doesn't matter. Sometimes you're writing software dedicated to a particular microcontroller and it expects the thing to be wired a certain way in order to run anyway.

oh well.. yes if consumer and producer is the same one, I guess it's all good! :)

The cast operator is why I can cast my struct directly to an "array" of bytes and stash it in a file. It makes me happy. It's so elegant. So concise. And so dangerous.

I've read this subject line several times now, wanting to point out what's so wrong with it. Anyway, I think you will love Javascript.

Neither did I, until I discovered I "was using it wrong" and had some "true C++ programmer" abusing templates lambda functions like there was no tomorrow.

The C++ one is even more accurate when pointers are involved !

You could always use a union, no need to even cast then (: I wouldn't want to program in C targeting a PC these days; but it is good for 8 & 16 bit embedded work, where you need to get at hardware registers and only have maybe 2K RAM and 16K or 32K ROM.

If you were using [fwrite](https://en.cppreference.com/w/c/io/fwrite), you wouldn't even need a cast...

Dang! I chased FAR too many pointers! :laugh:

I use unions sometimes, but i only needed the cast in two places in the code that inspired this post, and it was all it was ever going to need. :)

I really liked being able to cast nearly anything to anything. For a cheap and easy (and not too secure) 'encryption' I'd just do something like:
union {
char * readable;
ulong * notSoMuch;
}and then you can trivially make a string unreadable by storing the int array in a text file (lots of options there, too, spaced or other-delimiters? left-zero-filled? Decryption is obvious - and really no overhead as all - I always though of it as the string and its encrypted version coexisting in different planes of their little universe.

I use the union technique for that in both C(++) and C#. I don't *always* use it in the former just because i hate declaring new types for one or two lines of code where it will be used. i don't really believe in security by obscurity in most cases, but it may be useful for shrouding source code.

I'm coding a microcontroller and technically I'm using C++ but barely because I am avoiding templates and the STL. =(

I have been using C for+/- 32 years and still like it a lot. The fact that yes, you can do anything, does force you to be very careful what you ask for because you will get it. :-\
It's very satisfying to be back to it after being confined to coding in C# so much.

That doesn't sound like C. The only place in C where types are not enforced are in void pointers. Everywhere else you have to literally force the compiler to accept incorrect types. How is this different from other languages?

You misunderstand me. I'm not saying C doesn't enforce types. I'm saying if you want to change the type it's enforcing you just have to give it a little nudge. For example
struct S {
int x;
int y;
};...
S s;
s.x=1;
s.y=1;byte* bp = (byte*)&s;
// now i can work on it as a series of bytes
