File I/O

[kas2002]

ok
I want to make a program that allows you to login and sign up.
I have it all done except for I want to make it so when you sign up each time it creates a different file. I don't want to specify the file name I want the file to be user name the person inputs when they are signing up I tried this

ofstream a_file(name".txt);

and

ofstream a_file(name>>".txt);

and this

char txt[6]=".txt"; ................
...............ofstream a_file(name>>txt

and

ofstream a_file(nametxt);

I have all the other code there I just didn't want to include it all.
well I am pretty much baffled so please can someone out there help me. Thanx

From what you've posted I think strcat should do the trick. Something like this:

char name[12];
cout<<"Enter username (must be 8 or less characters):"<<"\n"
cin>>name;
strcat(name,".txt");
ofstream a_file;
a_file.open(name);
