this program is simply for recording data of various staffs.Inheritance has been used for taking additional data.Staff is the base class.the classes officer,typist and teacher are the derived classes.again the classes regular and casual are derived from the class typist.
now my problem is that whenever i call the constructor functions of respective classes,it gives an error saying no match to function call.can anyone help me with this. i dont get why the call doesnt match as all the arugments match....???

    }while(option!=0);
    }

the error is no match to function calls.

Edited 2 Years Ago by aanchal_1: forgot explain the question..:p

Try
t[i] = teacher(name,code,sub,pub);
and similarly for others.

While I'm here, you've got variable length arrays, which are illegal in C++ and your compiler really shouldn't let you have that, and you're using char arrays where proper string objects would be better and easier.

thanks.. it worked..but why didnt my way work?
yes,i'll make sure not to use it next time.. :)
