creat file for data in output folder

Sep 4th, 2008

Hii,

I have output from computation code called cdof and it is double. i want to creat a file either

cdof.log or cdof.dat where i can store values of cdof after each iteration or time step.

Please suggest me how to create files using iostream.

Thanks

Tip, use #include <fstream>

, wont do your homework, but a tip i know is welcome

its prety easy to use fstream, you can then call the classes you need to do the work you are looking for.

void main() { printf(" w00t "); return 0; }
