Advanced C with Linux

Advanced C programming is the level of C programming that goes beyond the basic syntax and concepts of the language and covers more complex and challenging topics that require deeper understanding and practice. Some of the advanced C programming concepts are:

  • Dynamic memory allocation, which is the ability to allocate and deallocate memory at runtime using functions like malloc(), calloc(), realloc() and free().
  • Debugging with gdb, which is a tool that helps you find and fix errors in your C programs by allowing you to examine and modify variables, set breakpoints, run commands, and more.
  • Function pointers, which are variables that can store the address of a function and can be used to call the function or pass it as an argument to another function.
  • Recursion in C, which is a technique of defining a function that calls itself to solve smaller subproblems until a base case is reached.
  • Typecasting and typedef in C, which are ways of changing the data type of a variable or creating a new name for an existing data type.

To learn advanced C programming, you need to have a solid foundation of the basic C programming concepts and skills.

Linux OS concepts are the basic and advanced topics that help you understand how the Linux operating system works and how to use it effectively. Some of the Linux OS concepts are:

  • Linux kernel, which is the core component of the Linux OS that manages the system’s hardware and resources, such as CPU, memory, disk, network, etc.
  • Linux shell, which is a program that provides a command line interface (CLI) to interact with the Linux OS and run commands.
  • Linux filesystem, which is a way of organizing and storing files and directories on a disk or other storage device.
  • Linux processes, which are instances of running programs that have a unique process identification number (PID) and can be controlled by signals.
  • Linux users and groups, which are ways of managing access and permissions to files and resources on a Linux system.
  • Linux packages and package managers, which are collections of files and metadata that provide software installation, removal, and update functionality on a Linux system.
  • Linux networking, which is a set of protocols and tools that enable communication between Linux systems and other devices on a network.

To learn Linux OS concepts, you need to have some familiarity with using a terminal and running commands. You also need to practice working with different aspects of the Linux OS, such as files, processes, users, packages, and networking.
