I'm working with a Ruby project for school, and have sadly not been able to find an answer to this question in my literature. I have an array of camping lots, each containing a guest. I initialize the lots like this: lots = Array.new for i in (1..36) lots[i] = Lot.new(i) end Further down I create a Guest object, initialize it, an...
I have this var checkBox = e.target; var tableRow = checkBox.parentNode.parentNode; var key = tableRow.attributes["key"]; var aKey = key.nodeValue; at this point aKey = "[123]" what the best way to return 123 as an int in javascript? note that aKey could just as likely be "[5555555555555555555]" so I can't just grab c...

I am not sure what is the use of square brackets. push @data, [ split //, $line ]; #printing this array gives crap values Or to put into other words what is the difference between the above and the following? push @data, (split//, $line); #printing this gives actual values Any sugg...
Hi, I have a bidimensional Object array in Java. Some indices aren´t nor used, because thei were skipped during array fill. Array looks like: Array[0][0] Array[0][1] Array[0][2] Array[1][0] Array[1][1] Array[1][2] Array[3][0] Array[3][1] Array[3][2] The 2 is missing, how can i rebuild the indices to make the array "correct"? ...
The output of eg >>w = whos; returns an array of structs. I would like to construct an array whose elements are the scalars from a particular field name in each struct.

In .net, does a bool[] use one bit or one byte per array item? ie, does it automatically pack the bool values? I know a single bool uses 1 byte, but maybe the CLR has a special case for bool[]... ...

Are there any concurrency problems with one thread reading from one index of an array, while another thread writes to another index of the array, as long as the indices are different? e.g. (this example not necessarily recommended for real use, only to illustrate my point) class Test1 { static final private int N = 4096; fi...

If I have int x[10] and int *y, how can I tell the difference between the two? I have two ideas: sizeof() is different. &x has different type --- int (*p)[10] = &x works but not int **q = &x. Any others? In some template library code, I need to determine whether a pointer is a "real" pointer or degenerated from an array...
