remaining three subjects "data structure" 60, "Database system principle" 67, "C + + program Design" 83. And these three subjects in addition to English, is the degree examination subjects. If you want to examinations a large degree certificate, the average score of all the subjects must be more than 70 points, just past.You say I'm not a cow? Do you think it's easy to teach yourself a test?However, if I told you, I am a freshman, just learn to play C language to participate in the "Blue Bridge

The single Namingstrategy protocol, in effect, separates the current pattern of concerns like Implicitnamingstrategy and Physicalnamingstrategy. And the Namingstrategy protocol is often inflexible enough to properly apply a given naming "Rules" should also be a lack
