Back in the days, people have to make a choice of 32-bit or 64-bit in choosing computers. Even now when we go to any website to download any game or program, we are asked to choose between 32-bit or 64-bit. And the only difference in them is, computers with 64-bit processors are more capable since it can handle more data at once. A 64-bit processor is capable of accessing over four billion times the physical memory of a 32-bit processor.
After giving a small lecture on 64-bit, let’s jump to the topic of this post, which is using windows.h header file in Turbo-C.
What does header files do?
The head task of header files for Windows API is to enable us to create 32-bit and 64-bit applications. They include declarations for both Unicode and ANSI versions of the API.
Windows.h is a particular header file for C and C++ languages which contains (as I told before) declarations for all the functions in the Windows API, common macros, and all the data types.
Windows API, also called WinAPI, is the core set of API(application programming interfaces) which is available in windows operating systems. For example, Win32 API, and that can be added to a project by including header file.
