Well, you haven''t told us in which language the stuff should be done.

Notice that "for loop" is just an iteration. I really don''t think you can clear an array without doing iteration at all...

However, in ANSI C you could use the memset() function... of course it does some kind of iteration to clear the array, but you haven''t to code it by yourself.

If you''re programming for Win32, ZeroMemory is a handy function. And if you''re just clearing an array, coding a for loop takes a few seconds longer and is slightly more error prone than calling a function.

It's Win32 and sweet. Took 15 seconds compared to 10 minutes with for loops. That was the reason. In order to speed up the map loading time I had to avoid writing 0s.

ZeroMemory(↦,sizeof(map);
