In recent years, the rapid development of China's real estate industry, industry integration has become a trend, gradually from regional development into a group of cross-regional integrated developers. However, for the ultra-conventional speed of the development of real estate enterprises, the challenges they face is also ultra-conventional. It is a very complicated system engineering to make scientific decision and balance resources rationally in the same time, under the limited capital and ma

because the field name of the field we created is problematic (whether the system holds the field or exists and conflicts, etc.), and the SQL statement syntax is normal but still does not save the article properly.In addition, some of the similar problems on the network reflect the fact that if you add a field simply by changing the " model field configuration (text mode)" column when creating a model, you do not create a field by clicking the "Add Field" button, because it is a façade, The fie

Information such as "Memory access violation" or "segmentation violation" usually means that a pointer variable contains a pseudo-address. One common reason is that initializing a variable fails.The result of free (p) is that the address to which P is pointing does not change, but the data at that address is undefined at this time.Occasionally, when your program uses a lot of space, the system may not meet your requirements for the new unit.

In this way, my programming is a real starter.At that time I knew that there is a discipline such as data structure, but also heard that the subject is very important, but I do not know why it is important, and even think that learning seems to be no use. So then we learned C #, and began to learn to drag the control. After that, I started looking for a job.Finally, this y

the direction of the resulting baseline case.(3) Design rules.Assume that all recursive calls can be run. This is an important rule because it means that when designing a recursive program, it is generally not necessary to know the details of the overhead management, and the computer can work out the complex details without having to trace a large number of recursive calls to the view.(4) The principle of synthetic benefit.Do not perform repetitive work in different recursive invocations when s
