Want to know computer for programming? we have a huge selection of computer for programming information on alibabacloud.com
First of all, it should be clear that programming does not require any mathematical and physical knowledge. At most, it only requires numbers, 1, 2, 3, 4, and 5. Mathematical knowledge is used only when a program is used to solve mathematical problems. Generally, network applications, file processing, segmentation, data extraction, and report notifications do not require any mathematical knowledge. The main content of
Abstract:Due to busy work, many people only focus on implementing the basic functions of the program, while ignoring programming specifications. The result is that the written code is hard to understand, and even reading their own code is very difficult, this results in a waste of time and reduced work efficiency. The code written by experts is easy to understand. How can we do it like them? "The first is progr

advanced languages is a regression. We may never be able to recover from this failure. -- Charles Hoare First, learn computer science and those theories, then explore your own programming style, and then forget about those. -- George carrette I am worried that the fate of the new object-oriented system will be similar to that of lisp. They can do a lot of things, but the weight of a complex class will c

Using these computer languages, people can create a wonderful world. You click on a webpage or install an application software, the simple action behind, is through the comput
The computer course of NetEase Cloud class opens up the course of programming language in the same time. Python, C language, Java, is to choose a study or all learn? Will it be easy to confuse three of them at the same time? Reply content:The main question is a very magical one. I am waiting for the older generation of non-net-class programmers to miss this problem, because in the entry of a language to hav
