what's rust??

??
is it a c dialect or sth???

Name: Anonymous 2017-02-07 15:17

Rust is a relatively new programming language supported by Mozilla, intended as a replacement for systems programming languages like C/C++. It's not a dialect of C per se, but does unsurprisingly borrow some features from C. It has some features borrowed from the functional programming paradigm, and intends to be ``safer" than C through compile-time features, such that this ``safe" code is no slower than ``unsafe" C code. The Rust compiler currently produces excessively large binaries, though that is at least part due to currently requiring static linking, since most operating systems these days don't yet come with a Rust runtime installed.

I've never even heard of an sth language before.

All of the Ruby on Rails latte-sipping webdev social-justice zombies moved to Rust. Combined with the fact that Mozilla is based in a heavily communist country proves that it is a Marxist conspiracy meant to destroy every other programming language, library and software project. I mean, it's in the name. Rust.

Their Rust to C transpiler is even named Corrode, because they want to corrode away everything that is C and C++. And they actively go around bullying people into rewriting software in their shitty language that is half broken just as Ruby was. The original creator of the language, Graydon Hoare, is a full on Marxist and part of a genocide cult known as The Voluntary Human Extinction Movement. He even links to it on his website.

C and C++ were originally created to ``corrode'' systems programming and CPU design.

C and C++ are the only languages that can't run on tagged architectures because of the pointer model and weak type system.

not true, you can convert C to languages that don't expose pointers.
https://github.com/vsedach/Vacietis

Name: Anonymous 2017-02-09 23:47

>>14
Vacietis uses the memory model of Common Lisp as is, so sizeof of the primitive data types (char, int, float etc.) is all 1. This shouldn't be a problem for most C code, but some C programs claim to be portable while making assumptions that things can be cast into an array of chars to be manipulated. These programs won't work under Vacietis.
That's not C. The ``things can be cast into an array of chars to be manipulated'' is why C is C.

C has the most requirements for pointers out of any programming language. Even more than ones where pointers are integers which are indexes into a flat address space.

Show me where in the C standard these requirements are written.

You can have that attribute if you compiled to something other than common lisp though, it has nothing to do with exposing machine addresses

C lets you read a pointer as an array of chars. That isn't compatible with garbage collection or tagged memory.

What's your definition of real array?

Name: Anonymous 2017-02-15 6:35

Bounds and type protection, methods which don't require implicit assumptions about how your data is mapped to the stack or heap.
What passes for an array in C would be scoffed at in any other language, because they are nothing more than alternative formatting for a pointer offset.

Lol idiot. Arrays are supposed to be contigious by definition. That is an assumption everyone should be able to make.

I see you finished CSC 100 my sophomoric friend.
It is easy to say a C array is contiguous when you know it is. It is not so easy when you are dealing with unreliable data streams and potentially malformed strings. You end up having to fall back on the assumption that your data is of length X and type Y, which only works until it doesn't. Then you are on your own.

C pointers can be addressed as arrays. C arrays "decay" into pointers when passed to functions.
(there is also a "decay" operator unary +)

No, nothing in a high-level language requires arrays to be stored in memory in a specific way. The array might actually be stored as some kind of tree, but you will never be able to find out from inside the language itself because the language semantics won't let you.

No, an array is not an abstract datatype like e.g. a stack or ahash table. It is specifically a contigious datastructure irrespective of language. Otherwise Haskell arrays wouldn't be implemented like C arrays. In fact, in all real languages arrays are contigious.

She's saying that you shouldn't assume arrays are contiguous in C, because any program written in a language that is not purely functional is susceptible to undefined behavior.

Arrays are allowed to be non-contiguous if your program has undefined behavior.

``Undefined behavior'' means it's defined somewhere else. Only functional languages like Haskell have your domain theory ``bottom'' scam because they don't have behavior, just equations.

Wrong, it means that it's undefined.

Only in the spec, any usable implementation will do something and can therefore be defined empirically, even if it's halt and catch fire.

In C, it probably means: either the compiler will define it for you at compile time, or the architecture will define it at runtime, or a mixture of both. It it sort of defined but may change any moment (even during the same program run).

That's technically correct but practically meaningless. Undefined behavior of the C language practically means that relying on any meaning for this behavior is complete non-sense.
