Now in learning C #, I find it difficult to find the programming exercise questions, I went to the bookstore yesterday, I didn't find it, I can't find it online. I have to find some C programming questions to practice hands. I have discovered myself, and many things I have learned are not much remember, or I still have to look back. It seems that some predecessors are right, learning and programming must do their own, every routine must enter the computer, only this can deepen the impression.
