[Dev-C++] locale , to .

[Zodiaq <zo...@ac...>]

Hello all Dev-cpp-users,

  is there a way to force treting , in numbers as . ?? In Poland there is a
strange habit of writing numbers this way:
number,fraction   13,75
no usual:
number.fraction 13.75

using ifstream extraction loses fraction value... there is way to read line,
and replace each , with . then use istringstream on in and at last use
normal extraction... lot of work - maybe there is other simplier way??

For most modern c/c++ libraries it should be enough to change locale
(setlocale in ANSI/POSIX) before using the input/output functions.

The normal C locale is hard-coded to a dot as decimal separator.

Yes, I know exactly what you are talking about. C++ has already solved 
this problem with the use of locales and facets, but that is not related 
to Dev-cpp.
However, there is a book that will help you, is called "Standard C++ 
IOStreams and Locales" isbn: 0-201-18395-1.
I am right now working on a class called Money, it addresses problems 
like the one you are having.
Let me know if you need any help, I would more than glad to help!

I have installed FLTK in the 'C:\cygwin\usr\include\FL' folder, but I 
don't know how to make Dev-C++ find the new library.
Can anyone help?

TIA

You should link your library in the project.(Project->Project =
Options->LinkerOptions) Add a line like=20
-lfltk(or whatever your library is called). Library names are like =
libfoo.a, but you should strip the starting "lib", so you should write =
-lfoo.
