[RESOLVED] No File Output?

[cypher5783]

My girl has been taking a C++ Programming Class @ Baylor in Waco, TX. I've been trying to help her and I can't seem to see why the file does not output. Everything looks like it should check out. Program Runs without any runtime errors. Compiler Gives no errors or warnings at all. But output File is null. I know the variable being output has value due to the display statement to screen. So anybody with an idea plz feel free to speak up. Cheers!

Sorry guys, Right after i asked this question we found the issue. The compiler while it showed termination of the program after running it didn't release it from the system. The .exe still showed up under the Task Manager. When all 20 of the duplicate .exe's were removed the program functioned normally.
