so here i have fixed your code error
the problem with your code is that you have just defined the functions first and class later so it cant find the class Employee in your code.
You have to first define the class then you can declare the methods then defined the main method of class and then give the defination of functions
or
You have to first define the class then you can declare and define the methods then defined the main method of class in c++ programming
