How to Run C Programs With or Without Code::Blocks | GCC & Custom Header Files

In this tutorial, I demonstrate how to compile and run C programs using Code::Blocks and directly from the Windows Command Prompt using GCC, without relying on an IDE. I also explain how to create and use custom header files in C programs involving multiple source files. English subtitles are available. Enable CC in the YouTube player for better clarity. Topics covered: Creating and running a C program in Code::Blocks Understanding the difference between an IDE and a compiler Compilation, object files, linking, and executable files Understanding GCC options such as -c and -o Compiling and running C programs from the Command Prompt Creating a Code::Blocks project Creating custom header files (.h) and implementation files (.c) Declaring and defining functions across multiple files Using #include, #define, and function prototypes Compiling and linking multiple C source files using GCC Example GCC commands: Compile a single C file: gcc main.c -o main.exe Compile and link multiple C files: gcc main.c custom.c -o main.exe The main takeaway is that an IDE like Code::Blocks is optional. You can write C programs using any text editor and compile them using GCC, provided the compiler is installed and properly configured.
