Exercise O9 Using the class Date that you have defined in exercise O7, write the definition of the class named Employee with the following private data members: first name - class string (the default first name is the null string ) last name - class string (the default last name is the null string ) ID number - integer (the default ID number is 999999) birth day - class Date (the default birth day is the default date: 1/1/1960) date hired - class Date (the default date of hire is 1/1/20011) base pay - double precision (the default base pay is $0.00) In addition to the constructors, the class has the following public member functions:

void readPInfo( ) that reads the values for the data members first name, last name, ID number, birth day, and date of hire.

void readPayInfo( ) that reads the value for the base pay data member. void printPInfo( ) that outputs the values of the data members first name, last name, ID number, birth day, and date of hire. void setBpay( double newBpay ) that sets the value of the base pay to the new value, newBpay. double getBpay( ) that returns the value of the base pay data member. double getGpay( ) that returns the value of the gross pay (which is the base pay). double computeTax( ) that computes the tax deduction on the gross pay and returns it as follows: 2011 Gilbert Ndjatou Page 88 If gross pay is greater than or equal to 1000, 20% of the gross pay; If 800 <= gross pay < 1000, 18% of gross pay If 600 <= gross pay < 800, 15% of gross pay Otherwise, 10 % of the gross pay. void printPayInfo( ) that outputs the gross pay, tax deduction, and net pay (gross pay - tax deduction). Place the definition of this class in the header file Employee.h, and the definitions of the member functions in the source file Employee.cpp. Note: - the header files string and Date.h must be included in the header file Employee.h and the header file Employee.h must be included in the source file Employee.cpp. - The header file Employee.h must look like the following: #ifndef EMPLOYEE_H #define EMPLOYEE_H #include using namespace std; #include Date.h Enter the class here #endif
