[QUOTE=abhimanipal;1222615] Yes after 7 the code will indeed produce 9 and 9 is not a prime number. But the input number will never be divisible by 9. So if the input is 27, the code will divide it first by 3 to get 9 and then again by 3 to …

Error messages are pretty straightforward - non-reentrant library code can't be executed in the same time by several threads (2 threads in this case). You must use semaphores (mutex) to lock shared resources between threads in such a way, that shared resource is accessed by only 1 thread at a …

[QUOTE=sourabhtripathi;1212221]how shd i do only declaration then !! extern int a; ??? is this right !![/QUOTE] Yes.

From my point of view, actor is entity, which: 1. Initiates actions in the whole system 2. Is outside of any system In this point of view, you are using too much actors here. So that the *real* actor maybe only web user. The rest - should be system-system interaction …

Hey, bounding-boxes is most simple collision detection method. What you didn't understood in that gamedev code exactly ? Ok. If you want even MORE simple collision detection you can use this- circle-circle collision method. Collision will be when: [ICODE]d <= r1 + r2[/ICODE], here d -> distance between circles centers. …

you can try something with loop, kind of: [CODE] scanf("%d", &k); for (int i=0; i<k; i++) { printf(" "); scanf("%d", &k_number); } [/CODE]

There is no such reduction formula which could map hash to it's input value. As such all reduction formulas *maps* hash to any value randomly, with the hope that at some iteration reduction formula will accidentally point to good password (aka. input to hash). So this is just probabilistic algorithm. …
