c99 - What is wrong with using turbo C?

Question

I always find that some people (a majority from India) are using turbo C. I cannot find any reason to use such outdated compiler... But I don't know what reasons to give when trying to tell them to use modern compiler(gcc,msvc,...).

Answer 1

Turbo C is a DOS only product. This means that it no longer runs "natively" on 64-bit versions of Windows, and must be run inside the XP compatibility penalty box.
