He is also an honorary professor and is known as the "pied piper of the computer industry". He has more than ten years of rich experience in computer science and software development.
2. Background introduction
Due to the wide variety of computer programming languages, the difficulty varies, but many programmers believe that mastering the C language is enough to do the job. In fact, mastering C language is just the beginning of mastering programming languages. It is also important to master other programming languages. Mastering programming languages also helps with software project management, team collaboration, solving technical problems, and getting to the bottom of things. Therefore, it is also necessary to understand other programming languages and the differences between them.
The development history of computers is a context diagram consisting of hardware, operating systems, and application software. It has undergone tremendous changes from ancient times to the present. Early computers were mainly used for scientific calculations, such as engineering, mathematical modeling, physical experiments, etc. With the rise of the Internet, application fields such as network communications and e-commerce have become popular, and scientific research and manufacturing have turned to the rapid expansion of the Internet. Today, people increasingly rely on computers for various tasks, such as writing documents, processing data, editing videos, designing CAD drawings, etc. However, computer science knowledge is not necessary for programmers. As long as you master the basic knowledge of programming languages, algorithms and data structures, you can complete various complex tasks.
