Hello,
I am trying to make a computer game with a login page.
Basicly I want a binary file to keep track of people's usernames and passwords.
I am a beginner so I need help with the binary part; is there a way it can just record:

char username[20];
char password[20];

*note I know I used char instead of string. I don't think it matters but correct me elsewise.

Use strtol()

The tutorial cplusplus.com offers about file IO might be useful.

@PracticingProgramer that's exactly what I'm trying to do.

Okay, so what I'm trying to do is create a game that has avatars. I want a database to record the usernames and passwords, so I can login to that and it will load something.
everytime I see the binary files(http://www.cplusplus.com/doc/tutorial/files/) It talks about the size.
