Introduction to C language: History and context of the C language. Structure of a program in C. Compiling and running a C program. Basic syntax: Data types (integers, reals, characters, pointers, etc.). Variables and constants. Arithmetic, logical and comparison operators. Flow control: Control structures (if, else if, else, switch, etc.). Loops (for, while, do-while). Functions and procedures: Definition and calling of functions. Passing parameters. Return of values. Arrays and pointers: Declaration and use of arrays. Pointers and pointer operations. Dynamic memory allocation. Data structures: Structures. Enumerations. Enter exit : Using the library<stdio.h> for entry/exit. Reading and writing files. Preprocessor: Preprocessor directives (#define, #include, etc.). Using macros. Modular programming: Organizing code into source files and headers. Separate compilation. Error management : Handling syntax errors. Handling runtime errors. Using debugging techniques. Advanced programming (depending on course level): Recursive functions. Manipulation of character strings. Advanced use of pointers. Use of dynamic data structures (linked lists, stacks, files, etc.). Introduction to multithreaded programming (with the use of external libraries). Good programming practices: Comment the code. Name variables and functions meaningfully. Using consistent code formatting. Error and exception handling.
