RunC-without_warning_flag-KS

This comprehensive course covers the fundamentals and advanced concepts of C programming to build a solid foundation for your programming journey. You’ll learn about essential topics like data types, variables, constants, and C statements, along with deeper explorations of control flow in C, including for loops and conditional statements in C. You’ll also learn about C functions, scope of variables, function arguments, and work with arrays, strings, and pointers in C.

You’ll gain hands-on experience with dynamic memory allocation, stack vs. heap, C standard library, and advanced topics such as binary files, input and output streams, and header files. The course also teaches compiling in C, linking in C, and debugging with tools like GNU debugger (GDB) and gprof for code profiling. By mastering these concepts, you’ll confidently program in C and optimize your code using gcc optimization flags.

Learn C

No matter which operating system you are using (GNU/Linux, Mac, Windows), you will need at least two things:

1.  A way to edit source code files
2.  A C compiler (& debugger)

# GNU/Linux

You have it easy! Most GNU/Linux distributions include a **package manager** that allows you to quickly and easily install software from centralized, up-to-date repositories.

## Compiler

If you are using Ubuntu, just open up a terminal and type the following command to install the tools you need:

That’s it! Now you have a C compiler ([`gcc`](http://gcc.gnu.org/)) and a bunch of other developer tools including a debugger ([`gdb`](http://sources.redhat.com/gdb/)). You can verify you have `gcc` installed by typing:

## Code editors

When you write C source code, you save it in one or more plain (ASCII) text files. Any editor that is capable of reading and writing plain text files, can be used to work with C code.

For example, Ubuntu comes with a relatively nice GUI-based editor called **gedit**. It has multiple tabs, it has #key# syntax highlighting: Syntax highlighting in code editors is a feature that renders different parts of a code (such as keywords) in different colors to help make the code more readable. #key# for source code (not only for C but other languages as well) and it has various plugins for adding other functionality.

Some other classic editors include [GNU Emacs](https://en.wikipedia.org/wiki/Emacs) and [Vi](https://en.wikipedia.org/wiki/Vi) / [Vim](https://en.wikipedia.org/wiki/Vim_(text_editor)). We won’t get into an editor war here, but suffice it to say that both are powerful and useful, and both have relatively steep learning curves. If you're unsure about which to choose, then I suggest starting with gedit.

There’s a pretty good cross-platform (linux, Mac OS X, Windows) source-code oriented editor called [Sublime Text 4](http://www.sublimetext.com/) that I can also recommend. It has a lot of neat functionality that’s particularly oriented towards source code editing (in many languages, not just C). Check it out.
