The header is the gateway to (Portable Operating System Interface) standards, allowing your C or C++ programs to talk directly to Unix-like operating systems like Linux and macOS. It stands for " Uni x St an d ard" and contains the "magic" functions that handle files, processes, and system-level hardware interactions. 📂 File Handling
