memory space. The process is often seen as a synonym for a program or application, however, a separate application that the user sees may actually be a set of mutually collaborative processes. To facilitate communication between processes, most operating systems support interprocess communication (IPC), such as pipes and sockets. IPC not only supports communication on the same system, but also supports different systems. NBSP; Most implementations of the Java Virtual machine are single-pro

1. The array name is a pointer constant representing the first address of the array space, and the constant assignment is not allowed in the program.such as int a[]; A is the array name, which represents the pointer constant of the first address of the array controlA = 0; is wrong and does not allow assigning values to pointer constants2. You can point to a constant by the pointer, but you cannot modify the contents of the constant through the pointersuch as: Char *p;p = "Testing"*p = ' 0 ';3.So

-oriented programming language, the Java language implements the object-oriented theory, which allows programmers to do complex programming in an elegant way.

not see the very big effect, because the work is no longer to the school as all the knowledge has the systematic study. In the internet age, all the information needed can be easily found through search engines, which is an era when you have to find useful and systematic sorting out for yourself, or more laborious. So we need to have a second choice, how to shorten their learning path, how to improve their competitiveness. We can not work blindly, but need to choose a good platform to learn. Do

On the road ahead, clear all obstacles, and you will surely go this way again, and next time you come here, you will find that there are no obstacles on the way. This is how software is developed.Maybe it will take you a little more time to solve this problem. But in the long run, it will help you save more time.　　When adding new features, we will first clean up the code needed for this feature. Take a moment to gradually clean u

Record your views on the technology to the documentation/blogIn our daily work, we may learn new things, new ways of doing things, practical forms and architectural ideas. You can record these ideas in a document or blog and share them with you.Because the way you're going to solve the problem is probably just another corner of the world. Ano
