Can someone please simplify the following 2 lines of code.

GolamMostafa:
It is in the conceptual world!

No, it's a clarification, nothing in the code is made simpler.

GolamMostafa:
The meaning is well clarified here (to me): if (inString [inCount] == EndMarker) break;.
Yet, the OP could not follow it; because, it was not simple enough for him.

No, it was too simple for him.
