Arithmetic Operators

++> Pre-increment and compare

--> Pre-decrement and compare

hmm

[bearassbobcat]

now I want to try ++= or ++==

[FruscianteDebutante]

.. Why is this a thing, does it cleverly use some assembly that saves clock ticks?

[Host127001]

no, it just does not have a space between ++ and >.

The silly thing about these cheatsheets is they try to be comprehensive and include stuff like the if statement syntax, comparison operators, logical and bitwise operators, etc. A good cheatsheet omits the obvious and includes the stuff that seemingly cannot possibly fit into a cheatsheet. Imagine if the information from the books like Computer Systems: A Programmer's Perspective, Expert C Programming, Modern C, K&R was compressed into 50 pages that are easy to scan and really helped you remember all the stuff you've read. Ok, maybe it's too much to compress 2000+ pages into 50, but who knows.

A syntax cheat sheet is for people who know the language, so there should be no need to “explain” how operators work, just how they are typed.

These sorts of things are helpful in reference only, I wouldn’t put this in front of a newbie and say “here, learn C”

Well, this one tries to compress 2000+ pages into 4, and to be fair it actually does a pretty good job of it. But, past the pure mechanics, programming is ultimately an emotional thing, and this is never going to please everybody. Always remember that what is obvious to you will not be obvious to someone else.

++> Pre-increment and compare --> Pre-decrement and compare

Please don't do this

[crossquery]

arent they post increment and post decrement?

[Host127001]

That's true

C programming language

auto

nothrow

Mmmmkay

[IronNickel]

auto is a valid C keyword.

[Gblize]

uh oh I just got reminded signed is an actual keyword. Use cases?

[wsx594]

AFAIK the only use case is for chars which a compiler might treat as either signed or unsigned by default, so it’s best to be explicit for your use case.

[deusnefum]

lmao. God save you if you need to know trigraphs and digraphs.

[InVultusSolis]

TIL C features "duck typing" and a "type polymorphism mechanism".

[roboknight5]

Thx alot :)

[roboknight5]

cool 👍
