            for (int A=0; A<30; A++)
                cout<<"-";
            DAT();
        }
}


It gives the error when compiled saying dn.dadd() is invalid call. Idk what is wrong? Please help!!!

What you've posted is not sufficient to compile your program.

@AbstractionAnon I know! But even if I call dadd function from main, it doesn't work!
Please help me out here!

If you're not going to post enough code to compile your program, then I am very limited in what I can comment on.

Line 14: Why is dn global? Globals should be avoided.

Line 24-27: You're referencing some kind of address structure, but you haven't shown a declaration for such an address structure. docnur certainly does not contain this address structure. Hopefully, you haven't declared this as a global variable also.

Line 18,21,29,31: Where is ch declared? It should be a local variable within docnur:dadd().

Line 44: gotos should be avoided. Use a loop.

Request for member which is of non-class type 'char'.


line 10: docnur has a char data member called dn
line 14: an object called dn is instantiated
line 55: the dadd function is called within itself dn.dadd();

It sounds like there's confusion with the same name being used for different things and dadd() is trying to be called on the char variable, which is not valid.
