newbie: how to pass input to quantlib exe

[matteo zorzi]

Hi,

I'm a newbie in quantlib and I'm interested in how to interface an application with quantilib.

Specifically, for test purpose, I'd need to integrate quantlib to an application, so I would like to feed any of the quantlib executable with an input (from input file ,  standard input or  arguments) and publish the output through the interface that I'm developing. I've tried a couple of exec files but I can't pass any input, they seem generate the output without the need of an input.

Can you please suggest a way to do it or eventually any link where I can find this information?


Thanks,

Matteo

Yes, the examples use built-in values for convenience.
If you want to get external input, there are quite a few ways to do that
depending on what you want.  From input file, the simplest way would be
to use an istream; ditto for standard input, for which you can use
std::cin (you'll find this covered in any C++ book).  For arguments, you
might have a look at the Boost Program Options library at
<http://www.boost.org/doc/libs/1_44_0/doc/html/program_options.html>.
