Adding Arrays

I never tried to add arrays before, assuming it would just give a syntax error. Strangely, it does not. Not that it seems to do anything at all.

SuperStrict

Local x:Int[] = [1,2]
Local y:Int[] = [2,-1]

x:+y	'???

Print x[0]+","+x[1]	'Prints "1,2"

Should this syntax do anything, or was my initial guess correct?

I find it weird it's not a syntax error, if I'm not supposed to do that.

There is no reason this should not work. x[0] refers to an integer, same for x[1]
and both is automatically converted to strings.

You might possibly be adding the Int Pointer of the Y array to the Int Pointer of the X array?

Aren't you just concatenating arrays x and y? I.e. you should end up with x[] having 4 elements [1,2,2,-1] after the line x:+y.

Test Code

SuperStrict

Local x:Int[] = [1,2]
Local y:Int[] = [2,-1]

x:+y	'???

For Local i% = 0 Until x.length
	Print "x[" + i + "]: " + x<i>[i]</i>
Next

Array concatenation was added in BlitzMax v1.26 (see Versions.doc in the BlitzMax installation directory).

thats not what he did up there.


Sure it would concatenate but he just outputed the content of the fields.

I think he expected that y[0] would be added to x[0] and so on.

Thanks for clarifying. I indeed thought it would either add the fields one by one or do nothing. Should have guessed it would concatenate, or at least I should have tried.
