How to read binary(data) file generated by Fortran in C/C++?
Is it possible? If possible how to realize it?
The binary file generated by Fortran is a double precision data file.
I have tried to use read binary file in C++, but have problem. The following
is my C++
code.
double temp=0.0;
ifstream File("bin.data",i

c++的 double size可能和Fortran不一样
and be aware of header

Did the Fortran program use "direct access" or "sequential access" to
write the binary file?
If "sequential access", each write statement will produce one record
in the data file, and the record is prefixed and postfixed with the
integer value that is the length of that record. For example
open(unit=..., file="...", access="sequential", form="unformatted")
write(unit=...)1.23d0
will write the four-byte integer "8", the eight-byte double "1.23d0",
and again the four-byte integer "8". The "8

This works.
Thank you very much!
