Hi guys I am looking for excellent online C only guides (not C++). I have learned Python over the last few months and have done the first 85 project euler problems to learn along the way.

I can't find any guides that are correct, that also have exercises for me to do. I was hoping "Learn C the Hard Way" would be good as I initially learnt Python from "Learn Python the Hard Way" but as it is in an alpha version some of its content is not fully correct.

Plleeeease please please please suggest a good online guide if you know one I will love love love you.

import java.util.Scanner;


public class Alternating
{
public static void main(String args[])

{ Scanner var = new Scanner(System.in);
int num1, num2, num3, num4;

System.out.println("Please enter first variable:");
num1 = var.nextInt();
System.out.println("Please enter second variable");
num2 = var.nextInt();
System.out.println("Please enter third variable");
num3 = var.nextInt();
System.out.println("Please enter fourth variable");
num4 = var.nextInt();

if(num1 < num2 && num2 > num3 && num3 < num4)
System.out.println("Alternating");
else
System.out.println("Not Alternating");
}
}

Your program only works for the case where num1 is the smaller number of the first 2, if the order is different but still alternating, it fails.
Testcase: 9 1 8 2

if(num1 < num2 && num2 > num3 && num3 < num4 || num1 > num2 && num2 < num3 && num3 > num4)

Quick question. What sort of environment do you guys use when you program with Python on Windows or otherwise? I was thinking of getting Cygwin, is that recommended?

You don't need any environments for Python unless you're going to be managing a huge library. Just write some text, save the file and double click it to run.

In any case, I recently moved to Sublime Text 2 and it absolutely crushes all the other IDEs and text editors I've used. Notepad++ loads a bit faster, but Sublime Text 2 is a lot better feature wise, and it doesn't feel clunky like an IDE does.

Apparently XCode can't print at my school, yet other applications like Word can so I have to copy+paste code into a Word Document to print it at school. Is this at all normal?

Also, my teacher has been looking for an online book of Programming in C (4.0, not 3.0).

edit: And my teacher just recently realized the reason computers weren't printing was because of XCode. We also can't correctly perform scanf statements yet either so we are basically stalled every couple weeks on one subject until the next subject is fixed T.T

To make matters worse, since the people that actually help with computers throughout the school are being overworked during the beginning of the school year and then under-worked towards the end there are only 2.

It's been one day yo. And anyone who doesn't use a Mac can't comment. And everyone who hasn't had printing issues with XCode can't comment. Judging by a Google on that, no one has had any but you.

Also, if you are writing standard C programs, regardless of the text editor, scanf should work, otherwise your teacher is doing something wrong. Try to compile and run the C file via the Terminal please. You can write a C file in any text editor

Apparently the is we can't do certain things like scanf without an administrative user and pass and so they would have to make us admins, but if they do that, then trololol is totally going to occur. So, they have to figure out how to make us admins for just XCode but nothing else or find a workaround. Plus, since we have to do this with school we have to do it via rules and directions given by our teacher. One idea around the class is for it to be made for kids to be able to do all the actual programming at school so that if kids can't get their hands on things like XCode they don't have to worry. One of the reasons for these bugs is that this is a new class in the school, and they actually changed stuff about it during the Summer(Went from C++ to C).

So, they have to figure out how to make us admins for just XCode but nothing else or find a workaround.

draconian access privileges is usually due to incompetence, because they don't understand security properly, they just block rights to everything

That's the proper way to handle security. Incompetence would be trying to explicitly block individual things and allow the rest.

Thing is my school chooses #2 because they don't have enough staff. 2 People to cover at least 150-200 computers? (Estimated)
