Greetings,
for an array byte[3][3] myArr, I can code myArr[0] = 5 and have:
5,5,5
0,0,0
0,0,0
Can I perform a similar assignment to the column? This,
myArr[][0] = 5, doesn't work.
This works fine for small arrays, but for large arrays such
access pattern is cache unfriendly. It's usually best to redesign
the code to avoid assignments to columns if possible (for
example, by working with a transposed array). The language is not
providing a convenient shortcut for something that is usually
undesirable and expensive. And I think that this is actually
reasonable.
