3. A company's finance department needs to develop a program that calculates employee salaries. The company has 3 types of employees. The wages of the workers are the hourly
salary (set by the member function) multiplied by the working hours of the month (set by the member function) plus the salary of the seniority; the salary of the salesman
is the hourly salary (set by the member function) Set by member function) multiplied by the working hours of the month (set by member function)
plus plus seniority wages, where the sales commission is equal to the amount of goods sold by the salesperson in the current month (set by member function) 1% of the salary;
the salary of management personnel is the basic salary of 1,000 yuan plus seniority salary.
Seniority wages means that the monthly wages of employees will increase by 35 yuan for each additional year of service in the company . Please use the object-oriented method to analyze and design this program, and write a complete
program in C++ language.
