Edited 3 Months Ago by pritaeas: Moved.

s11 is an employee and also a person. It is not a student!
s11 is not a meaningful name, try to give more meaningful names to your variables.
If you would have named s11 as AnEployee or something, you would have noticed that AnEployee.Informatio_student(); does not work. You first have to create a new student class.
Hope this helps.

On line 25 declare your class public. It is missing so it's default accessor is private.
