   • What is another name for natural numbers?

     The Number System is a system for representing numbers on the Number Line using a collection of symbols and rules. These symbols, which range from 0 to 9, are referred to as digits. The Number System is used to accomplish mathematical computations ranging from complex scientific calculations to simple counting of gifts or the number of books left in the box. Numerous types of number systems exist, each with a different base value for its digits.

     Natural Numbers

     Natural numbers, which include all positive integers from 1 to infinity, are a part of the number system. Natural numbers, which do not include zero or negative numbers, are also known as counting numbers. Counting numbers like 1, 2, 3, 4, 5, 6…, etc. They are only positive integers, not zero, fractions, decimals, or negative numbers, and they are a part of real numbers. All integers greater than 0 are natural numbers. Natural Numbers Examples are 9, 21, 45, 987, 100112, and so forth are only a few.

   • What is the written-out word for O_EXCL

     Top Answer

     Answered Jul 21, 2021 · 20 votes

     The real meaning of O_EXCL is "error if create and file exists" but the name is derived from "EXCL

     usive", which is a bit misleading though and causes many people to misinterpret that flag.

     Opening a file with O_EXCL will not give you exclusive access to it as some people incorrectly assume. A file opened with O_EXCL by one process can be be opened by other processes for reading and even writing at the very same time, no problem, so access is clearly not exclusive.

     The main reason why this flag exists are "lock files". Long before there was file advisory locking (with fcntl) and semaphores/mutexes that can be shared among processes, a simple way was required to ensure atomic access to certain system resources across multiple processes. The way to realize that were lock files. The first process that wanted to have access to a resource would create a lock file in /var/lock to claim ownership of that resource and delete it again once done with it. Other processes would monitor that directory and thus know if a resource is available or not.

     The problem: If two processes look into the directory and both see that a certain file is not present, so the resource is available, and now both try to create this file, how to ensure that only one of both will ever succeed? And that's where O_EXCL comes into play. If they both try to create that files with O_EXCL set, this operation will only succeed for one of them and that's the process which now owns the resource lock.

     So O_EXCL is not for getting exclusive access to a file, it is for making exclusive access files whose purpose is to regulate exclusive access to some kind of resource.

     The second most important usage of O_EXCL today is file access security. Consider this case: A root process wants to create a file and fill it with content that only the root user shall be able to ever see, not ordinary users, but it is creating it in a directory ordinary users do have write access to (e.g. /tmp). If the process would create the file as follows

     open("/tmp/root-only", O_CREAT | O_WRONLY, 0600);-

     and the file does not exist, it is created, owned by root and only root has read and write access to it, so ordinary users cannot see its content. Mission accomplished.

     But what if an ordinary user has already created /tmp/root-only before? Then this file is owned by that user, this user can have read access to it and the open call above will just open the existing file. Even if the root process changes ownership and file permission directly after opening the file, this has no effect on a process that already has opened the file before (e.g. tail -f).

     So the correct way to implement that case is in fact:

     unlink("/tmp/root-only"); // best effort, may not even existopen("/tmp/root-only", O_CREAT | O_EXCL | O_WRONLY, 0600);-

     In case open does succeed, the process can rely that the file is owned by the process owner and nobody else has access permissions to read/write it.

   • What is the "base class" for numeric value types?

     Top Answer

     Answered May 06, 2009 · 30 votes

     The answer is: you don't need to provide overloads for ALL the numeric types, just for Double and Decimal. All others (except maybe some very unusually large ones) will be automatically converted to these.

     Not a base class but in fact that was the red herring. The base class System.ValueType doesn't help much as it includes types that are not numerics. The language reference i was reading was what got me confused in the first place :)

     (I was just looking for who to attribute the answer to and it was a combination of Scarecrow and Marc Gravell, but since they were comments i have put the answer here)

     There isn't one (or at least, not one that just means "numbers"). You could use:

     void Foo<T>(T value) where T : struct {...}-

     But that allows any struct - not just numbers. If you want to do arithmetic, generic operators may be of use. Other than that; overloads it the most viable option.

     What I do:

     public interface INumeric<T> { T Zero { get; } T One { get; } T MaxValue { get; } T MinValue { get; } T Add(T a, T b); // T Substract(.... // T Mult... } - public struct Numeric: INumeric<int>, INumeric<float>, INumeric<byte>, INumeric<decimal>, // INumeric<other types> { int INumeric<int>.Zero => 0; int INumeric<int>.One => 1; int INumeric<int>.MinValue => int.MinValue; int INumeric<int>.MaxValue => int.MaxValue; int INumeric<int>.Add(int x, int y) => x + y;- // other implementations... }-

     Now, you can use it in a method:

     bool IsZero<TNum, T>(TNum ops, T number) where TNum : INumeric<T>{ return number == ops.Zero; }-

     or extension method

     public static bool IsZero<TNum, T>(this TNum ops, T number) where TNum : INumeric<T> { return number == ops.Zero; }-

     and in your code:

     ... var n = new Numeric(); // can be an static prop- Console.WriteLine(IsZero(n, 5)); // false Console.WriteLine(IsZero(n, 0f)); // true Console.WriteLine(IsZero(n, "0")); // compiler error-

     or, with extension method:

     Console.WriteLine(n.IsZero(5)); // false Console.WriteLine(n.IsZero(0f)); // true Console.WriteLine(n.IsZero("0")); // compiler error-

     When you do a comparison between a and b, b will be promoted to unsigned int for the purposes of the comparison only, so the values will compare equal.
