Study Notes
C Language Overview
- Developed by Dennis M. Ritchie at Bell Labs to create the UNIX operating system.
- Initially implemented on the DEC PDP-11 computer in 1972.
- K&R standard, the first public description of C, was produced by Brian Kernighan and Dennis Ritchie in 1978.
- Widely used for system programming and applications in UNIX, C compilers, and many state-of-the-art software.
- Known for its ease of learning, structured approach, efficiency, and ability to handle low-level activities.
- Compiles on various computer platforms, making it versatile for developers.
- C is a successor to the B programming language, which emerged around 1970.
- Formalized by ANSI in 1988.
- Essential for implementing popular software like the Linux OS and RDBMS MySQL.
C Environment Setup
- Requires two software components: a Text Editor and a C Compiler.
Text Editor
- Used to write and save source code for C programs, typically with a ".c" extension.
- Examples include Windows Notepad, EMACS, vim, and vi; choice depends on the operating system.
- Essential to have familiarity with saving, compiling, and executing programs.
C Compiler
- Translates human-readable source code into machine language for execution by the CPU.
- GNU C/C++ Compiler is the most commonly used free compiler.
- Installation varies by operating system.
Installation on Different Operating Systems
UNIX/Linux
- Check if GCC is installed with the command:
$ gcc -v. - If installed, will display version information; if not, follow instructions on the GCC website.
Mac OS
- Obtain GCC through Xcode development environment from Apple's website.
- Simple installation instructions are provided on developer.apple.com.
Windows
- MinGW is needed to install GCC.
- Download from the MinGW homepage and run the installer.
- Install essential components: gcc-core, gcc-g++, binutils, and MinGW runtime.
- Update the PATH environment variable to include the MinGW bin directory for easy access to tools.
Conclusion
- C programming offers a robust framework for system and application development, with straightforward installation across various platforms, making it an enduring choice for software engineering professionals.
