Thread: Simple File and String Program Not Running

Hi my code is not running so I ask that someone test this for me and also review if my logic and syntax is correct.

The assignment is to write a program that statistically computes similarity of C syntax with another program; a same and a different. The one used here is in C language, it's called Battleship.cpp. The program must open a file and read line by line for keywords and then produce statistics.

The reason my code is not running is the fopen function is failing and it goes to return -1. I am using MS Visual Studio 2013 and there are no compiler errors after turning off deprecation. I do see, however, this error UMEngx86.dll'. Cannot find or open the PDB file. The file being opened is in my source folder.

Is the Battle_ship.cpp file located in the same directory as your executable?

It wasn't. Wow that made a huge difference. Now how do I make the window stop so I can see the stats?

If you're using Visual Studio then you can select DEBUG->Start Without Debugging to start your program and then the console window should stick around even after your program has exited.
