Program compiles, but doesn't act?

quayda (61)
Could someone please help me understand why this program is compiling, but not running? The console window opens, but shuts just as fast. I'm thinking I need to write something to the files so that the program will merge what has been written, or will it read two files that are already composed?? It's meant to merge the two input files to the output file, big picture. I need to alphabetize the output, but I can do that once I figure out how this thing writes to the output file! Thanks!

Run the program from the commandline.

Thanks for the link @admkrk
I think I thought the console closing meant something different because I've never called external files before. I think I was being silly and thought that the program must be doing things I can't see with these files I can't see. Lol. But, now I've got the console to stay open. The program is failing with the first file....not sure how to fix that ailment. Am I calling everything correctly in my declaration and definitions?
