The Daily CLAD

Re: Oh the nostalgia: 2 of 10

What are the values of String Out, Boolean Out, Numeric Out and Numeric Array Out following execution of the VI?

NOTE: The original post "The Daily CLAD" - post number 9, can be found here. Oh the nostalgia!!

a) String Out = "SteveLikesLabVIEW", Boolean Out = TRUE, Numeric Out = 5, Numeric Array Out = {0}

b) String Out = "SteveLikesLabVIEW", Boolean Out = FALSE, Numeric Out = 5, Numeric Array Out = {0,1,2}

c) String Out = <empty string>, Boolean Out = FALSE, Numeric Out = 0, Numeric Array Out = {0}

d) String Out = <empty string>, Boolean Out = FALSE, Numeric Out = 0, Numeric Array Out = <empty array>

LabVIEW sets the count terminal to the smallest value of the count terminal (here is 5) and input array sizes wired to the auto-indexed tunnels (here are 0 and 3) thus the smallest value of these (5, 0, 3) is 0 so the For loop will iterate zero times and will keep default values to its output tunnels

The default values for the data types here are

String = <empty string>

Boolean = FALSE

Numeric = 0

Array = <empty array>

Its D obviously. The loop count terminal is '0'

Answer is "D"

Answer: D. Nice one all.

The loop does not iterate, as controlled by the auto-indexing input tunnel connected to the smaller of the two arrays (the empty array). LabVIEW has to create values for the output tunnels of the FOR Loop and goes for the default values.
