Can someone please simplify the following 2 lines of code.

Thank you UKHeliBob for the reply, but still my first question: is about ending the if condition line with a ;

and starting with the {do something code} as if the if condition is still open.

And what about

(++inCount<inLength);

is it equivalent to?
if ((inCount+1)<inLength)
{
inCount=inCount+1;
}
