Program exited with code 0

Hi everyone
I'm having a problem with running a given code. The code is to solve some unsteady flow question and it really is supposed to work. It is an .f file with input.dat and output.dat. What I have done is creating a new project, then inserted the .f file under the source files and built it. So it built just fine, but the when i tried to run it it says
'Question 1.exe': Loaded 'C:\Windows\SYSTEM32\ntdll.dll', Symbols loaded.
'Question 1.exe': Loaded 'C:\Windows\system32\kernel32.dll', Symbols loaded.
'Question 1.exe': Loaded 'C:\Windows\system32\KERNELBASE.dll', Symbols loaded.
The program '[8004] Question 1.exe: 0' has exited with code 0 (0x0).

What is wrong with it and What am I supposed to do?

Many thanks

Honna

1) How are you supplying the input and output files - is it on the command line or are the names hardcoded? If the names are hardcoded, maybe the result is already in your output file.
2) Are you running this from an IDE or from the command line? If IDE, which IDE.
