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.

# Short vs explicit

As a general rule, explicit code should be preferred over using “tricks” to make code extremely short. There is a trade-off, of course. Short, tricky code is less code, but the tradeoff is that it may be more difficult to understand by others, and even by ourselves as code authors, when we return to the code after some period of time. Finding the optimal tradeoff between concise and clear is something we should be thinking about, and something that will be different for everyone.

If you want to see some examples of ridiculously “tricky” code, there is a competition called "The International Obfuscated C Code Contest". Here is an example, from the 2011 IOCCC Competition, the entry called [eastman](http://www.ioccc.org/years.html#2011_eastman) by Peter Eastman:
