I know C is really outdated, and it has security vulnerabliities if you encounter undefined behaviour by accident

or well
just don't cause UB
here is a hint: -fsanitize=undefined to gcc
it helps catch runtime UB

Great language. My mistake. Outdated gives it a bad wrap. It is a good language that exists for many, many years.
steady juniper
Thanks.
wild kayak
also `-Wall -Wextra` can help at compile-time
basically enables most extra warnings
which I have found to be helpful
rocky valley
C is perfectly adequate

you can write vulnerabilities in any language

Agree
sharp sandal
wants to learn programming
being a based god, chooses c
being even more based, chooses this book
well, you're starting out better than i did,
make sure to pass -std=c89 and -pedantic to your compiler as well
or you might get weird warnings since the code in the book is... well, ansi c and the compiler doesn't know that
sinful jay
to add to those opinions, you should always use -Wpedantic -Wall -Wextra -Werror locally, that part on -std=... makes sense due to the book using dated things, sanitizers offer additional runtime checks, which are not totally bulletproof, but useful, so you may want to run your programs after compiling them with e.g. -fsanitize=address,undefined, those all things together will help you catch a lots of problems
sharp sandal
thanks for aggregating the suggestions :)
sinful jay
the code on the screenshot has a problem that should be pointed out by compiler with warnings enabled
sinful jay
at the beginning of the thread
sharp sandal
oh lemme scroll up
sinful jay
the very first message
sinful jay
no, that's not it
sinful jay
(I mean if you assumed it is C89 then it would be a problem, the missing return, but then the other problem is also there, but completely different than in later C)
sinful jay
idk? the declaration of celsius twice?
correct
sharp sandal
pheww
sinful jay
in C89 you cannot declare in for, in later you leave unused variable
and that will be noticed
sharp sandal
i thought there was a \m at first because of crappy windows font rendering
sharp sandal
in C89 you cannot declare in `for`, in later you leave unused variable
ah
anyways op if you want to do something really fun make a random passphrase generator
load up an english dictionary wordlist
randomly pick one word
rinse and repeat until you have enough words in the passphrase
