CLAD2017 - Answer the requirement: What are the odds of that

[SercoSteveB]

You are tasked to write a VI that accepts an array of positive numeric values (Data Array In) and outputs an array that contains all of the odd numbers found in the input array (Odd Data Samples Out).  Which of the following VIs satisfies those requirements?

NOTE:  For all case structures the only case not shown is the Default and in all instances that is wired Array Input Tunnel to Array Output Tunnel as shown:   

Have a go at writing a VI yourself or expand the Spoiler tag to see the possible answers.

When you use the And function, comparing some number with a 1, what is LabVIEW checking? Is it just comparing the Least Significant Bit of the number with the 1?

[crossrulz]

The AND is a bitwise function.  1&1 = 1, all others = 0.  So when you AND a number with 1, you are just masking the least significant bit (LSb).  That LSb represents 2^0 = 1.  So if you AND an integer with 1 and the result is 1, you have an odd number.

Hello everyone!

In accordance with exercise description, the option that gives us the output which matches with "And" operation and "Not Equal To 0?" function is letter A.
