What do you mean, "need to amend syntax"?

Give us a clear, complete and precise descritption of your problem. The more you help us, the more we can help you.

Sure! How to avoid Compilation errors below?
I've added Date Class and its data members to combine with Employee derived classes.
I need to stay in this context and make the program work

If i try to rollback with single Employee Class and Date, it works fine when i create new object and take half arguments from Employee class, half from Date Class Function.
If try to add derived class and declare virtual functions, compiler throws errors:

Employee.h:24:14: error: ‘virtual void Employee::print() const’ cannot be overloaded with ‘void Employee::print() const’
24 | virtual void print() const; // virtual
| ^~~~~

The first problem are the default paramters:

1
2
 
SalariedEmployee( const std::string &, const std::string &,
const std::string &, double = 0.0, int, int ,int);


The compiler requires that all default parameters (like double = 0.0) has to be at the end of the parameter list. So either remove the default = 0.0 or change the order of the parameter.

I would suggest that you solve the default paramter problem first and then trying to figure out that mysterious 'Employee::print()' problem.
