HOW TO BECOME PROFICIENT IN C

Name: Anonymous 2011-04-15 17:42

So I claimed I was proficient in a number of languages on my resume, all of which I've barely used.

I think I can get away with some of it but I really think I need to know how to use C and Python well for the job. He said the job might require C# which is close enough to core C.

How do I become proficient with these languages in a week or so?

$ cat test.c
int main() { return 0; }
$ gcc test.c -ansi -pedantic -Wall -Werror -Wextra

wow, you actually told pretty much everything other than actual error. have you ever actually take a programming class?

Well, how the fuck else do you think I recognized the errors in that shit code you fucking fat jew?

Can you rewrite it appropriately?

If anyone can help me out I don't understand what "Undefined behavior. Ie, there some are systems where you won't see the output until *after* the program exits." means.

I'm kind of new at this. I did take a programming course but the class ended before getting to better programming habits.

do not listen to him. he was just pointing to stupid things while missing the obvious error.

use realloc instead of second malloc. you are malloc ing new memory and lose the old address (which gives a memory leak btw) this new address points to a new memory location which is filled with garbage. it does not contain old data.

Ok, I did end up getting the program to work but I am still curious about the errors that guy mentioned. I understand all the problems except for the one I quoted (though I also don't know how to fix the scanf problem.)

Basically it was just pointing out that i/o can be buffered. You need to use flush if you want to be sure it will actually be printed then and there.

And what happens if part of the memory is actually the CPU registers? Does it still have an address you bitch?

Yes, but most modern computer use this concept called virtual memory. On top of that, most os's will fucking load the damn program into the cache before it executes it.

[quote]Undefined behavior. Ie, there some are systems where you won't see the output until *after* the program exits.[/quote]
Just use fflush(3) or setvbuf(3) if you're seriously worried about this.

>>49
[quote]I also don't know how to fix the scanf problem.[/quote]
scanf(3) returns the number of tokens which have been successfully scanned.  If this number doesn't match the number of tokens in your format string, you know have a problem.

Just read the man pages, it's all in there.

An undefined behaviour is a behaviour that's not defined. It could do anything, even rape you're anus.

Undefined behavior is sometimes known as a semantic error.

I refuse to read this thread.
However:
C# which is close enough to core C
You will never be hired by anyone, ever.  Not even for a non-programming job.

That's not what I said, faggot. That's what the recruiterbro said. The guy that is hired to find applicants. He also said C++ is really similar to C.
