So I have been tasked with picking an operating system (windows 7) and finding out what language it's written in. (C C++ C#) Now I also have to pick 3 user applications that Windows 7 supports and find out what language they're written in. I have chosen Internet Explorer, Photoshop and Sony Vegas. Internet Explorer : Photoshop: C++ Sony Vegas: I cannot find anything for the languages for the other 2. If anyone would be so kind as to link me to an information page. Thanks!
