Difference between dos and c programming?

Answer: In dos you have to create the complete application, yourself in other Words the complete .EXE file, that can be done in any of the many different programming languishes IE. GWBasic, QBasic, C, or ASM etc., the last is the most difficult but the result is the fastest application. Where Windows is a platform for your application, most of the things you want to do is already created in Windows, all you have to do, is to use it from within your application, not that it means less programming, you actually have to do more coding than with Dos, for instance in Dos GWBasic, if you want to read data from a comm. port you just open it as follow

[code]

open "comm1:" for input as #1

input #1, var

close #1

[/code]

But in Windows it is a long story
