I finished my code a while ago, but my computer had to be fixed and they reset rhe OS. Although, I was able to save all the data before it was fixed. I had the VS 2013, but now I have the 2015 version. The code was working perfectly, but now it skips instructions and I have no idea what's the problem. I could paste it here, but it's 1000+ lines.
It is not skipping that instruction; you have leftover input in the input stream and it is reading that. Please read: http://www.LB-Stuff.com/user-input
The problem is not specific to any version of any compiler. Your program has multiple ways to reach line 620, some of which may or may not leave unread input in the buffer. It is likely that while using VS2013 you never triggered the issue, or if you did you didn't notice it, or possibly forgot. Either way, the issue has always been there and changing your compiler version did not make it magically appear.
