struct _X
{
int field1;
int field2;
int field3;
} anArray[15];for (int i = 0; i < 15; ++i)
{
anArray[i].field1 = 1;
}for (int i = 0; i < 15; ++i)
{
anArray[i].field2 = 2;
}for (int i = 0; i < 15; ++i)
{
anArray[i].field3 = 3;
}Really horrible, poor guy didn't consider performance of such code. I have far more superior solution:
anArray[0].field1 = 1;
anArray[1].field1 = 1;
anArray[2].field1 = 1;
anArray[3].field1 = 1;
anArray[4].field1 = 1;
anArray[5].field1 = 1;
anArray[6].field1 = 1;
anArray[7].field1 = 1;
anArray[8].field1 = 1;
anArray[9].field1 = 1;
anArray[10].field1 = 1;
anArray[11].field1 = 1;
anArray[12].field1 = 1;
anArray[13].field1 = 1;
anArray[14].field1 = 1;anArray[0].field2 = 2;
anArray[1].field2 = 2;

No matter what language - all of them allow at least for summarizing this in one loop construct... :) Regards Thomas

some languages such as C# allow for code inside a struct; C does not. How would you do it in C? :)

that is something different, it generates no run-time code. It may or may not be sufficient for what the original program needed, assuming you duplicate the constants 15 times. :)

Can't modify a deleted message :P I couldn't make it scalable so I deleted my post:
struct k[15] = { {1,2,3},...}

No, however you can edit a message instead of deleting it. :)

Well, this can be a coding guideline. It may look a bit silly and pedantic to put brackets around a single statement, because it makes you write things like:
if (somecondition)
{
return;
}Tools like e.g. ReSharper (for C#) do that automatically, so you don't have to type. I've seen this often in larger teams, and it brings some more readability to the code. I do it myself... Or, as you suggest, it's simply an absence of any thinking or understanding. Who knows ? :cool: Regards Thomas

Excactly - even though I don't subscribe to it, it is a common guideline to avoid a mistake like this:
for (int i = 0; i < 15; ++i)
anArray[i].field1 = 1;
someotherarray[i].somefield = 2;It's just a strange idea, but someone, in the future, MIGHT come up with maybe another array to be assigned a different value. :rolleyes:

Do you get paid by LOC ;)
Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]
That would go
// Set field to 1:
anArray
[
// index
0
].
// field name
field1// value
1;Don't attribute to stupidity what can be equally well explained by buerocracy.
