How to Run

On Local Compiler (Recommended)

1. Open the code in Code::Blocks, Dev-C++, or any offline C compiler.
2. Build and run the program normally.
3. You’ll experience smooth clear-screen transitions between menus.

On Online Compiler (Limited Behavior)

• Some online compilers do not support the system("cls") or system("clear") command.
• In such environments, the program still works, but the clear-screen effect may not display properly.
• If you see text shifting or stacking instead of clearing, that’s normal in restricted environments.
