What Happens When You Run a C Program? | Source Code vs Executable vs Process | EP01
📚 Execution Awareness Series — Episode 1 (FLAGSHIP)
What really happens when you run a C program?
Most people think: Write → Compile → Run
But execution is much deeper.
A source file is not an executable.
An executable is not a process.
In this episode, we start building Execution Awareness using the most famous program ever written — Hello World.
🧠 You will learn:
• Why source code ≠ executable ≠ process
• What actually happens after pressing Run
• How Linux sees a running program
• Why execution knowledge improves debugging and system design
This episode builds the foundation for:
Linux Internals • System Programming • ELF • Runtime • Embedded Systems
