In the WHODUNIT problem set in week 3 it says:
"Open up bmp.h, and you’ll see actual definitions of those headers we’ve mentioned, adapted from Microsoft’s own implementations thereof. In addition, that file defines BYTE, DWORD, LONG, and WORD, data types normally found in the world of Windows programming. Notice how they’re just aliases for primitives with which you are (hopefully) already familiar"
I'm not familiar with what he just said. Can anyone offer clarification on what he is talking about?
