If the decision on the training institutions, "the best, cautious, to avoid being cheated" what is best, the training institutions are not the more famous, the higher the tuition fees must be better. In fact, a lot of training organizations to fight the fierce advertising, in fact, the teaching level may not

subtraction, randomly generating 0,1,2,3, representing subtraction respectively. Note: (1) Taking into account that pupils have not learned negative numbers, so in the subtraction, if the presence of minuend greater than the meiosis, will be two number exchange, and then subtraction;(2) Considering that the divisor can not be 0, if the divisor is 0, then generate a random number, using while loop;(3) in each operation and the IF-ELSE structure is divided into a variety of situations, in which t

network programming, and generally does not need to care about how the IP layer handles the data.At present, the popular network programming model is the client/server (c/s) structure. That is, both sides of the communication are waiting for the client to request and respond as a server. The customer requests the server when the service is required. Server generally as a daemon always run, listen to the ne
