You are inputting data that represents a circle. The circle data includes an x position, a y position, and a radius. All three pieces of data are double precision. In the future, you might need to store the color of the circle, represented as an integer. How should you represent the circle on your front panel window.

  1. Three separate controls for the two positions and the radius
  2. A cluster containing all of the data
  3. A type definition containing a cluster
  4. An array with three elements

  2. Wire directly to the indicator terminal
  3. Use a local variable
  4. Use a functional global variable

Formula nodes accept which of the following operations?

  1. Basic programming language instructions Input and Print
  2. Embedding of subVIs within the Formula Node
  3. Pre and post increment (++) and decrement (–) as in the C language
  4. The use of nested Formula Node structures.

A coercion dot indicates that:

  1. The data types are consistent
  2. A polymorphic operation will be performed on the data
  3. A data buffer is created to handle the data conversion
  4. Data values are being coerced because they are out of range

You customize a control, select Control from the Type Def. Status pull-down menu, and save the control as a .ctl file. You then use an instance of the custom control on your front panel window. If you open the .ctl file and modify the control, does the control on the front panel window change?

  1. Yes
  2. No

You develop a subVI that only outputs a value and need to use this subVI in a (calling) VI. Which of the following is the best way to enforce dataflow to control the execution of the subVI?

  1. Use the subVI in a sequence structure
  2. Modify the subVI to have dummy inputs that can be used from the calling VI
  3. Modify the subVI to have Error clusters that can be used from the calling VI
  4. Modify the subVI to have a global variable and use it from the calling VI
