Don't worry, it's a common affliction! You're about to dive into the wonderful world of C programming, where the magic is real, but also, ridiculously, lower-level
So, let me tell you: text editors don't just dump data on your screen. They actually load the file's contents into memory (RAM), which is where the "magic" happens
Think of it like this: when you open a file in a text editor, here's what goes down:
1. **File system**: The OS looks for the file on disk and loads its contents into memory.
2. **Text editor**: The text editor reads the loaded data from RAM (your computer's RAM) and displays it on your screen.
But here's where things get interesting: when you edit a file, those changes don't just magically appear on disk; they actually modify the file's contents in memory
The OS will swap out some of that memory to free up space for other processes, but most of what happens is... well, magic
When you compile C code, it generates machine code (the language the computer understands) from your source code. The compiler translates that into binary data, which gets loaded into memory.
**The compilation process:**
1. **Preprocessing**: The preprocessor expands macros and includes header files.
2. **Compilation**: The compiler converts the source code to assembly code.
3. **Assembly**: Assembler code is converted to machine code.
That's when the real magic happens! The resulting binary data gets loaded into memory, where it can be executed by the CPU
**The execution process:**
1. **Memory management**: The OS manages memory allocation and deallocation for your program.
2. **CPU instructions**: Your program executes a sequence of CPU instructions, which are essentially machine code.
So, that's where you are today! You've got a glimpse into the mysterious world of C programming, where "magic" is just a fancy word for complex computer science
What do you think? Are you ready to dig deeper and learn more about this fascinating world?
