Elysia try the code first !!
iostream should not be included as fstream is inherited from iostream only!!
So for your kind information when fstream is included there's no need to include iostream

Secondly do you mean to say!!if i have 20 members in class i should take input of 20 members in main 1 by 1??and then write a function which takes 20 arguments and copies 1 by 1 to class members?!!!???That's pretty funny isn't it?
I did and it did not compile.Originally Posted by chottachatri
That is irrelevant. If you use something defined in the iostream header, then include it. It did not compile until I included the iostream header, which tells us a lot. Do it.iostream should not be included as fstream is inherited from iostream only!!

The code will be the same, in or outside the class.Secondly do you mean to say!!if i have 20 members in class i should take input of 20 members in main 1 by 1??and then write a function which takes 20 arguments and copies 1 by 1 to class members?!!!???
The class represents the data, it is the essence of the data, it does not ask FOR data. If it does, then you have the concept of classes wrong.
