Thank you for your answer! I will try to do that. My struct has 4 char arrays (array1[20]...) and 1 int, no pointers or anything.

Thank you for your help! I've done that and now I get error "stream.valid()" when trying to read. Read code:

int x = 1;

I've tried changing it and it was as Salem said. Well, I'm still learning, and our courses are going slowly. We haven't had any proper assignments yet, so I'm "winging" it on my own. Thank you for...

No, I did not. I haven't gotten any errors. I'm using Visual Studio 2019. And I do check for errors and warning messages. The only warning message I got was that types differ, since fopen returns int...

Found the solution! Thank you for taking your time and looking here!
