I came across the following while reading about how easy it is to redefine methods in Ruby:
class Array alias :old_length :length def length old_length / 2 end end puts [1, 2, 3].length
Sure, it's a bad idea, but it makes the point. But it bothered me...

To specify the name of the method rather than perform the method, you use a symbol .
Just writing length calls the method length .
Old_length, :length
A method isn't a symbol, but its name is.

How do I find the length of an array without using the Length property in C#?

Usage:
byte[] data = new byte[100]; int length = GetLength(data);
Implementation:
private = handle.AddrOfPinnedObject(); int offsetToArrayLength....
You can use Length Property right? If you are using Linq Name space you can use Count() extension.

Why do we have length of an array as an attribute. array.length and for String we have a method str.length() ?
Just came in my mind, is there some reason?

I guess the reason at the time of the design was performance) it needs to do a method call to get the length.
Size, length or similar things.

Hi people.
My question is very basic, but I didn't find an answer on a Google search.
In Java , ¿what is the maximum size a String object may have, referring to the length() method call?
I know that length() return the size of a String as a char [ ]

Considering the String class' length method returns an int , the maximum length that would be returned of the array.
Since arrays must be indexed with integers, the maximum length of an array is Integer.MAX_INT.

I need to store fixed-length (up to 8 digits) numbers produced from a variable length strings. The hash need not be unique. It just needs to change when input string changes. Is there a hash function in .Net that does this?
Thanks

I assume you are doing.
System.Security.Cryptography.MD5CryptoServiceProvider.ComputeHash to get a MD5 hash, truncate it to the desired length.

I understand the differences between CHAR and VARCHAR, one being fixed-length and the other variable-length, and that if all fields in a row are fixed-length, a table will generally perform better.
However, something that is unclear to me is that if I...

Obviously no, otherwise it wouldn't be called variable-length in the first place.
The CHAR and VARCHAR types are declared with a length that indicates characters.
No, it just sets the max size.

Look for something similar.

I've seen 8-bit, 16-bit, and 32-bit CRCs.
At what point do I need to jump to a wider CRC?
My gut reaction is that it is based on the data length:
1-100 bytes: 8-bit CRC 101 - 1000 bytes: 16-bit CRC 1001 - ??? bytes: 32-bit CRC EDIT: Looking at the Wikipedia...

The CRC should be chosen specifically for the length of the messages, it is not just.

I'm looking to write a method that creates an array of a fixed length (in my case 12) from any array it is provided of arbitrary length (though the length will always be 12 or less) by repeating the objects in order.
So for example given the array a:

<cfset.
The condition being that your counter is less than or equal to the length of your array.
Down to the first, that way you won't try to reference an element past the array length after.
