Question

Define and implement the overloaded constructors that support the following test function for a StudentEmployee class. The data members for the StudentEmployee class are:

%u2022 age - integer number
%u2022 name - String
%u2022 DSI - String
%u2022 salary - floating point number

int main()
{ //s1 will take all default value
StudentEmployee s1();
//s2 will take all supplied values
StudentEmployee s2 (50, "Jackie Chan", "D87654321", 10000000.99);
//s3 will take supplied age value, name, DSI and salary will take default values
StudentEmployee s3 (25);
//s4 will take supplied age and name value, DSI and salary will take default values
StudentEmployee s4 (35, "Jenny");
//s5 will take supplied age, name and DSI value, salary will take default value
StudentEmployee s5 (45, "Jack", "D11223344");
//s6 will take supplied age, name and salary value, DSI will take default value
StudentEmployee s6 (60, "James Bond", 65000.0);
//s7 will take the same value of s2
StudentEmployee s7=s2;

//the rest of the code
}
