C language of the second week

Like a nightmare C language is over. Yes, the process is no less than the feeling of childbirth in a pregnant woman, extremely miserable. There is no code base at all I even forget a lot of math thinking. Here again to thank Xiao Teacher for my care, although he is our teacher, but the posture is very low, like a public servant. I seemed to see a different luster in his young face. It says "Hengmeilengdui cold on the thousand fingers, bow willing ox." "This kind of luster makes me more and more feel his kind kindness, in the heart that respect also grows thicker."

Master leads the door and the practice depends on the individual. Make a copy of the code to commemorate this Binghuangmaluan learning phase.
