RussianQuestion
I always find that some people (a majority from India) are using turbo C. I cannot find any reason to use such outdated compiler...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,...).
Solution
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.
OTHER TIPS
While there are plenty of reasons not to use Turbo C (it's old, predates standards, generates 16-bit code, etc.), it's not valid to answer a question like "How do I do X in Turbo C?" with "Just use GCC". That would be like somebody asking "How do I do X with my 1992 Toyota?" and you saying "Just get a newer car".
People who are using Turbo C are probably doing so because it's a requirement, not because they don't know about anything better. Odds are it's for a programming class where the assignments they turn in have to work in that compiler. When I was grading C++ assignments, it didn't matter what compiler the students used, but they had to compile and run properly with the compiler I was using.
I would say support and standards compliance would be the two big issues for me.
Good luck even finding Borland/Inprise/Borland/Codegear/Embarcadero, or whatever they call themselves nowadays. Even more kudos if you can get them to admit these products exist (although I did at some point get them from the Borland museum on BDN).
Performance can be important but the vast majority of applications I write spend 90% of their time waiting for the user (I don't do genome sequencing, SETI analysis or protein folding - the market is pretty small).
Honestly, if I have the choice between two free products (where obviously money is not an issue), I'll always select the best (that would be GCC for me).
Turbo C generates 16-bit X86 code. Kiiinda nice when you're developing on a 16-bit x86 processor.
Been there. Done that.
The pragmatic reasons for changing are: gcc is under development, with bug-fixes. It deploys on modern operating systems and modern chips natively.
It was also my first compiler (4 yrs ago), though I switched to gcc soon enough when I learned it didn't follow latest standards and relied on features that are considered deprecated or bad practice. These were enough reasons for me to make the switch.
The most important reason you should use decent C compiler is performance. Since GCC optimizes the code aggressively, the compiled programs would have the performance tens of percents higher than before.
Turbo C is much simpler to configure & use, runs on old DOS machines. Also it is compact in size.I guess that is the reason.
However, it does take a very little advantage of modern processors.
