read from input file and write to output file

[fuku123]

Hi, I want to run a c++ program on unix using input and output redirection to make them read from the appropriate input file and to write the putput to the appropriate output file.
What commands do I type?
example:
Prog.cpp reads from data.dat and writes to a file.

do i write:
g++ prog.cpp -o data.dat

Uh? If I've understood you correctly, you need to build it normally (say, you build an exec named prog.exe), and then execute it redirecting its input and output. Like:

$_> prog.exe < data.dat > output_file
