After finishing the blog there are problems and thoughts:

Teacher this week to decorate the task is after class carefully look at the second chapter content, and give the after-school reference exercises, the problem is after reading the textbook, still have a large number of lessons after the problem will not do, especially contains code, probably because the original C language

Foundation is not thick, so in the completion of some exercises is very difficult, and the blog is also written very simple, because think it only play a guide to the role of learning outline, the next will not find classmates help.
