Understanding the '#include <windows.h>' Preprocessor Directive in C/C++

The code '#include <windows.h>' is a preprocessor directive that includes the 'Windows.h' header file. This header file is a standard component of Windows operating systems, providing a collection of functions and macros that allow developers to interact directly with the Windows environment. By including 'Windows.h', programmers gain access to the Windows API (Application Programming Interface), which enables them to perform tasks like:

• Creating and managing windows
• Handling messages and events
• Creating dialog boxes
• Interacting with various aspects of the Windows operating system

In essence, the '#include <windows.h>' directive is crucial for any C/C++ program that aims to utilize the features and functionalities of the Windows operating system.
