HI,

i am Nishank and have got a project -to make periodic table by using the following
a. Data Structure
b. Object Oriented Programming in C++
c. Data File Handling
through the program the user should be able to:
a.view the periodic table
b.edit the periodic table
c.delete a record
d.quit


can anyone help me with it
i have made a file and here is the attachment
i am using turbo c++ as the compiler

While compiling it is showing me no error but while running it is showing the following errors:

Linking PERIDIC.EXE:
Linker Error: Undefined symbol _circle in module PERIDIC.CPP
Linker Error: Undefined symbol _setcolor in module PERIDIC.CPP

Can anyone help me correct it
please
And can anyone Help me do the Same thing without using
graphics.h and
dos.h


ALSO HERE IS THE CODE:::
