errors reading header files( i believe)

i am writing a program that is a gradebook. two classes are involved and when i try to compile my program i get this error.

student::student' : overloaded member function 'void (class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)' not found in 'student'

and i do not know how to fix it. i have tried to find the error in my header file, but i do not know what is wrong b/c i believe i have written the header files properly and i have included them in the cpp file. i am using microsoft visual if that makes a difference. any help would be much appreciated. thank you.
