Re: [Dev-C++] [Dec-C++]eof() function and type variable from file input

[Jason H. <jas...@bt...>]

No offence, but I'm having trouble working through your english. From what I
can gather you have a file which you need to read through and re-output in a
different format.

If you could provide an example of a valid input file (3 or 4 lines) and the
output file that it would convert to. You don't have to provide actual data,
just make it up if it's confidential. Maybe then we could work up something
that might work.

I don't know of any standard functions that determine for you whether
something is a float, int or string of somesort. It is assumed you would
know the file format or be able to work it out for yourself. It depends upon
how you choose to represent your data in the end.

I am currently working on a program that takes in a file and outputs
something else depending upon the contents of the input file. So all that
needs to be different is the code that deciphers the input and produces the
output.

Also Dev-C++ is just an environment for developing programs, the standard
compiler is MinGW, which isn't totally standards compliant but works well
enough.

Jason.
