• #include <windows.h>: This line includes the Windows header file, which provides access to various functions and definitions for Windows-specific programming.
• int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow): This is the entry point for a Windows GUI application. It is similar to the main function in a console application, but specifically for Windows GUI programs.
• MessageBox(NULL, "Hello, World!", "My First GUI Program", MB_OK): This line creates a message box with the text "Hello, World!" and the title "My First GUI Program". The MB_OK parameter specifies that the message box should display an OK button.
• return 0;: This statement exits the WinMain function and returns 0 to indicate successful program execution.
