Base on what I understood from this question, the N terminal indicates how many times the loop will run and it would depend on the input arrays as well as the value on the N terminal. The for loop always run the fewest time possible, in this case 3 times.

OK, I was wrong. First I don’t like this implementation of LabVIEW

1. To give this information via N means it is a redundant information. After finishing the loop i has the same information (n = i+1)

2. My optical first impression was you assign a value to N and later you read the value N so it should be the same

Later I recognized you can read N=3 in the first iteration of the loop. I did not expect this. Yes this makes sense! Now I like it 😉

Thank you Steve for this special Daily CLAD to clarify this .

A.  Another I didn't expect.  Thanks Steve!  That can be useful in troubleshooting!

Very tricky, I new that N will return the value it's been wired. But today I learned that it will give the maximum times the loop is runned.

Answer is A.

Answer: A.  Nice one DavidCorney, J_M_M, Juvin, LordNobady, HaraldBraun, danielb85, crossrulz, MrStevenUND, gnshmrthy, nik35324 & rgbernatchez

This one divided opinion. Andreas23 makes an interesting point, the N Terminal doesn't look like it should modify the value wired to it......but it does and it is actually useful for post loop iteration count processing.
