Is there a limit to how many times a loop can run in C? void main() { int T,N,x,X,i; x=0; scanf("%d", while(T>0) { T--; scanf("%d", X=0; while(N>0) { N--; scanf("%d", if(x>X){X=x;} } printf("Case: %d",x); } } T has a ra...
How do you make C use the For Loop Statement and generate this: 1 12 123 1234 12345 123456 1234567 12345678 I know this requires that the value "1" to be continuously be multiplied with "10" and added with "1". ...

I see the different conventions used in many books I had read, where you would create infinite loops with either loop structure such as: while() foo(); for(;;) foo(); But really, what are the differences I should know about? which one is better? ...
I currently have the following code: events.detect do |event| #detect does the block until the statement goes false self.event_status(event) == "no status" end What this does is output the instance of event (where events is a string of different Models that all collectively call Events) when the event_status method outputs a "no ...

Hi, is there a data structure or a pattern in Javascript that can be used for both fast lookup (by key, as with associative arrays) and for ordered looping? Right, now I am using object literals to store my data but I just disovered that Chrome does not maintain the order when looping over the property names. Is there a common way to ...
