Answer 1

the way you read files seems so weird to me. I'm not on a PC to test it myself but i believe that's the problem. When working with files you must always check if you reach the end of the file by calling eof(). Here is my code
```
ifstream inFile("IsAdmin.txt");
/*consider check for errors here
if (!inFine.is_open()) {handle the error}*/
string adminkah = "";
while(!inFile.eof())
{
getline(inFile, adminkah);
if (usernamePrive==adminkah)
{
inFile.close();
return 1;
}
}
inFile.close();
```

Sorry, I'm not really across c++, but maybe changing your login variable to a boolean True/False instead of a 0 could help. If the 0 and 1 already are that, maybe you need to check your break conditions in another way.

Answer 3

you guessed right, its the infinite loop. Why not use a multithread?
