I always find that some people (a majority from India) are using turbo C. I cannot find any reason to use such outdated compiler...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 wh
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.
