دانلود کتاب برنامه نویسی مدرن C – راهنمای برنامه نویسان برای یافتن تسلط و دور زدن موارد عجیب و غریب

C is a small but extensible language, with software libraries (standard and third party) extending the core language. Among high-level languages, C still sets the mark for performance; hence, C is well suited for applications, especially ones such as database systems and web servers that must perform at a high level. The syntax for C is straightforward, but with an oddity here and there. Anyone who programs in a contemporary high-level language already knows much of C syntax, as other languages have borrowed widely from C. C is also the dominant systems language: modern operating systems are written mostly in C, with assembly language accounting for the rest. Other programming languages routinely and transparently use standard library routines written in C. For example, when an application written in any other high-level language prints the Hello, world! greeting, it is a C library function that ultimately writes the message to the screen. The standard system libraries for input/output, networking, string processing, mathematics, security, cryptography, data encoding, and so on are likewise written mainly in C. To write a program in C is to write in the system’s native language.
