Comparing elements of array to input

If I read in a letter, or word from the user, how would i be able to compare it to see if it is equal to an item in the array.
ex. In the first slot of the array I have HELLO, and now the user types HELLO, how would I compare it to that item in the array?
thanks

if (array[0].equals(stringInputByUser))

How to compare the same array?

Hello,
The question not how to compare arrays.
I have a method that gives results of an array type int.
for(......){
int [] arrayFunc(int [] input)
return arrayOut;
}I want to compare those arrayOut arrays. I need to find a way to save the first output and then compare it with the newest output. Where do I have to put the temp array to temporary save the array? What should happen if I want to keep track of the results and get comparisons of first, second, third output?
Thanks

Still not 100% sure but I try and help. What you need to do is have two references. After you have generated a result compare it to the last result. After the comparison you need to assign the current result to the last result and then go around the loop again to generate a new current result. Below is some code that uses plain ints but I hope it illustrates what I am trying to explain.
import java.util.Scanner;
class ComparingNumbers {
public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    int current;
    System.out.print("Number: ");
    int last = scanner.nextInt();
    scanner.nextLine();
    for(int index = 0; index < 10; index++) {
      System.out.print("Number: ");
      current = scanner.nextInt();
      scanner.nextLine();
      System.out.println("Difference is " + Math.abs(current - last));
      last = current;
}

Comparing elements inside a vector

Hello,
I am having a hard time understanding how to compare elements inside a vector. I have a vector of six strings and I want to compare the first element at index 0 with all other elements at positions 1-5. After that, compare the element at position 1 with elements at positions 2-5 and so on until all elements have been compared against each other.
Can some one please advise me on how to achieve this?
Thank you.

How to disable an element of array?

Hi,
Here i have written VI that will make an array of meaningfull data, for example: data pattern 23 16 16 24
So whenever two consecutive 16 occurs, VI will delete one 16 from data pattern. But in my case wht problem i am facing is:
Whenever it deletes 16 from data pattern, it will show 0 in place of 16 but i need that cell fully disabled unless this 0 will count into mu data pattern.
So i am trying to use disable property node for greying that particular cell or can any tell me why 0 is coming into array when it deletes 16 from it.

Hi Puneet,
from what I see in your screenshot the described behaviour is resulting from an unhealthy combination of using (hell a lot of) locals in combination with "use default if unwired" case structure output tunnels
Remove locals (you already have a shift register, so use a wire instead!), use more descriptive names than "array", wire all output tunnels to avoid unwanted behaviour of your vi...
Why do you compare with an array (in your for loop) when you only need the result for the first element? Compare with scalar instead...
Why is "DLE Check" of type DBL? You only seem to use it as integer...
Why do you write to terminal "Array" and a local "Array" after the FOR loop? (Here is probably the root of the problem!) Only one of the write operations will be effective and you don't know which one...(possible explanation: the local array gets an array formed by autoindexing. So this array contains data for each iteration including an zero [because use of "default if unwired"] when you initially wanted to delete that very element!)
Aditional note:
Next time you attach a screenshot please use a picture format like PNG (as long as you don't use BMP)!

Merging elements of array

Hi,
I am new to programming.
I have a sensor that sends a data stream through a serial port. I have collect all that data in a 1D unsigned byte array. Now, lets say my 1-D array is [12][45][65][12]...... where each "[ ]" is a element of the array. Now to make sense of this data what i need to do is merge two elements the array and multipy it by 2/(2^15). i.e. My converted data should by [1245]*2/(2^15). Basically 2 bytes together makes sense. I can do a simple add of each element. Also the other problem is,data from the sensor is a stored as the 1-D array of unsigned byte. However, the converted data is supposed to be signed 16-bit integer.
Please give any suggestions on how to go about doing this.

Another option is "decimate&Join". (Here it is easy to change the byte order if needed).

The prefix mx for element mx:Array is not bound

Hi All
I have a component:
<?xml version="1.0" encoding="utf-8"?>
<mx:Array id="arr">
    <mx:Object label="Flex"
      thumbnailImage="http:/someURL"
      fullImage="http://someURL" />
</mx:Array>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
</mx:Canvas>
This gives me an error
The prefix "mx" for element "mx:Array" is not bound
I need a root element here, but I cannot use mx:Canvas, what would be the best choice?
cheers
Luca

Hi Luca,
Try to put the Array inside your canvas rather than outside ...
<?xml version="1.0" encoding="utf-8"?
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Array id="arr">
    <mx:Object label="Flex"
      thumbnailImage="http:/someURL"
      fullImage="http://someURL" />
</mx:Array>
</mx:Canvas>
Why you dont want to use mx:Canvas as root tag of your component.. ?? However which ever component you use try to put the <mx:Array/> inside your root tag of your component, otherwise you will be thrown the same error as mentioned. The error occurs as the the compiler doesn't recognize the namespace mx for the array since you declared it outside the root tag of your component.

Remove element from array

hi
if i have an array
eg
int[] array = {4,2,1,2,1};
how to i remove the index 2 from it and create a new array?
thanks

You can't remove the element--an array's size is fixed at creation.
If you want a new array, create a new one that's one element smaller, then use System.arrayCopy to copy the elements you want to keep.

How can i retrieve missing element in array

how can i retrieve missing element in arrays if array length is exceeded

Not sure about what the question means, but could it be that OP is not aware that the first element in an array is at index 0 (not 1) ?

Comparing elements in 2d array

Hi all
I need a solution. The problem is I have a 2-d array of numbers. I have to display a array subset such that the elements in the first row fall in the ranges provided by me through user prompt.

its like i have a 2d array of numbers in increasing order. i input a number and i have to get the output array as all the elements that are less than it in the same order.( or rather get a subarray upon comparing the elements )
OK, let's try to interpret this once more in clearer language. Apparently, the first row has some significance.
Maybe only the first row is increasing in value and we want to keep the subset of the 2D containing all columns that are below a threshold in the first element. Since the values in the first row are increasing, all we need to do is find the column index where the first element is too big, and then take the subset of the 2D array up to this point. Here is a solution for this interpretation of the task.
You still might need to adjust for detail, e.g. use "greater or equal?" instead of "greater?" depending on your exact needs.

Lock elements of array true when the input element becomes true

I am working on a project in which I want to create an alarm for any number of inputs. Any time that there is a input that is out of range, an alarm will be indicated. I would like the indicated alarm to persist until the user pushes a reset button, even if the out of range condition is removed. In addition, new alarm indication may occur and should also persist.
In the VI below, the Alarm Dummy Control is used to generate alarm(s). I want the Alarm Indicated array to maintain any element that had or currently has a true (alarm element). Every alarm will persist until the manual reset is pushed.
I am sure there is a simple solution, but I am drawing a blank right now.

You can operate on the array directly, no FOR loop needed.
Here's a very quick draft. See if it can give you some ideas.

Data Federator - Array as input to web service.

Hi,
I have an ASP.NET web service method that takes in an array of string for input. I am adding this web method as a data source in Data Federator. However when I look at the method's parameters in Operations Selection in Data Federator, the array of string becomes a string. It seems that Data Federator only passes one element value as an array to the method. Is there any way for Data Federator to see the array correctly so that I can pass an array of string to the web method via Data Federator?
Thanks.

hi,
Data Federator does not support array types as input parameters. For the moment there is no Data Federator workaround for this limitation (the only possibility is to modify the WebService definition).
thanks.

Compare elements of two or more clusters

Hello,
I am very new to labview and was hoping someone could help me with this. I am taking user input (motor #, size of steps, number of steps and sequence #) and storing all the data (for each motor) in a cluster.
(Now this is where I need help..)
I want to take the 4th element of each cluster (the sequence #) and sort it in order (1,2,3,4...). Based on the sequence number I want to use a flat sequence structure to send the commands to my motor controller in the right order.
Any help in solving this problem would be appreciated,
Regards,
Mridu

The reason Crossrulz said to put the Sequence # first in your Cluster is because sorting starts with the first element, then the second, etc. If, however, you require that the Sequence number be, say, the third element, you can still sort it by using a trick (only do this if the array of clusters isn't huge) -- create a temporary cluster whose first element is the Sequence # and whose remaining element is the entire cluster. An array of these things will sort on the first element. Once sorted, take the Cluster apart and return only the second element, your original Cluster, now sorted. [I hope that was clear ...]

PL/SQL Associative Array as INPUT Parameter

Hi,
Just wondering if anyone out there has a good example of how to get VB.NET (using ODP.NET 9.2.0.4) to pass an Associative Array as an Input parameter to a stored procedure (not for bulk binds)? Specifically, I'm looking for an example of how a VB Strong Typed Collection would be passed through the PLSQLAssociativeArray Collection Type.
I've managed to get a test to work by passing a 1-D String Array through the ODP.NET layer to the PL/SQL AssociativeArray parameter. But I've had zero success trying to get the Collection from VB through ODP.NET.
Thanks in advance for any help.
Todd.

For example, if I wanted to return a list of customer ids and names into A PLSQL Associative Array, how would I do it. I know how to return a list of customer ids into a PLSQL associative aray using the code below but I have to specify the maximum number of elements and the maximum size of each of the elements. Is there any way around this?
Dim prmOutCustomerIdList As New OracleParameter
With prmOutCustomerIdList
.ParameterName = "oCustomerIdList"
.CollectionType = OracleCollectionType.PLSQLAssociativeArray
.OracleDbType = OracleDbType.Varchar2
.Direction = ParameterDirection.Output
.Size = 5
.ArrayBindSize = New Integer(4) {10, 10, 10, 10, 10}
End With
