Comparing two results from same array

[mugulous]

For a project I am doing, I need to compare two co-oridnates that will be inputted into an array. The co ords in question are the first x and y, and the last x and y. The array will look as such (x1,y1,x2,y2,x3,y3 etc....). How do I choose the first and last two intergers of the array? Also the array will vary in length each time I run it.

You need exactly two functions: ArraySize and IndexArray.

ArraySize gives you the size of the array, and using just one (!) IndexArray you can get the elements with indices (0, 1, size-2, size-1)…

What have you tried so far? Where are you stuck?

This sounds like homework to actually learn LabVIEW: did you notice the Training resources in the header of the LabVIEW board?
