thank you tux4life

hi I am new in c++ although I am reading about ti for a while now :).
recently a made a silly code that I can not compile so please some help about it.
ps: befo you even star to read it the following errors ocure while compilling Undefined reference to :base_employ,menager,engineers,researcher

#include<iostream>

using namespace std;
