LabVIEW
array - doubt
Solved!

To answer your question: You are not understanding dataflow. Since there is no data dependency between the 2 loops then the 2 loops will run at the same time. However, the bottom loop will run with empty arrays since they are only populated once the top loop ends. Your incorrect use of local variables is a mistake, and the probably the number one reason why we see programs not working correctly. You have to ensure the arrays are populated before you try to use them. That said, there is no need for 2 loops to begin with. Perform the comparison right there where you are generating the random number. Use a shift register to accumulate an array. If the random number is larger than the control, then add it to the array. If not, pass the array through. Use a case structure. Like this:
To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.
You really should start out with a few tutorial, because you are missing very basic fundamentals of LabVIEW programming.
- The shift register needs to be initialized with an empty array, not with a scalar.
- Inside the case structure, you want a built array, not an initialize array. Makes no sense!
- You have an empty array container. You would need to populate it with elements of the correct type.
Here's a quick rewrite, maybe it can give you some ideas. SInce you are dealing with integers, you want blue for the arrays. 🙂
Good luck!
