To maximize the Turbo C++ window, you can follow these steps:

1. Launch Turbo C++: Start the Turbo C++ program on your computer.
2. Windowed Mode: By default, Turbo C++ opens in a windowed mode. If it’s not already in windowed mode, press the Alt+Enter key combination to switch to windowed mode.
3. Title Bar: Locate the title bar of the Turbo C++ window. It is the topmost bar that contains the name of the application.
4. Maximize Button: In the top-right corner of the title bar, there should be a button with an icon resembling a square. Click on this button to maximize the window.
5. Keyboard Shortcut: Alternatively, you can use the keyboard shortcut Alt+Space to open the window control menu. Then, press the ‘X’ key to maximize the window.

Once you perform one of these methods, the Turbo C++ window should expand to fill the entire screen, maximizing its size. You can now make full use of the larger workspace for coding and debugging.
