Explanation / Answer
/*
Since your program is correct logically, It has one compilation error that I fixed and the last function's difiniton is not explained correctly. So I modified it and Please find the working code below.
Let's understand Method Overloading.
Method Overloading: Method overloading is a technique in which we use the functioin with same name but different signatue.
You can overload a method by using following ways.
1.Changing number of parameter => Function name is same but number of parameter are different
2.Changing data types of parameters=> Function name is same and number of parameters are same but data type of parameters may differ.
example:In your given program you used function calcWeeklyPay() two time with same name. But in both the time the number of parameters are differing
let's see
1. double calcWeeklyPay(double annSalary)
2. double calcWeeklyPay(int hours,double payRate)
In above both the functions the function name is same but first function has only one parameter of double type and second funvction has two paremeters one int and another is double. This is called method overloading.
Important: you can not do method overloading by just changing return type.
like:
1. dobule sum(int x,int y)
2. int sum(int x,int y)
This is error in C++ method overloading.
Since I don't have difinition for contracted based employee so I can't add that method but I hope that you understood the method overloading ,now you can add one more definition of method calcWeeklyPay() for contracted employee.
Do below two thing.
Add one more case like.
case 'C' :
case 'c' :
cout << "What is your hourly rate? ";
cin >> hour;
//Like that you can add other parameters
cout << "The gross weekly pay is $";
//You can pass all that parameters to the below function.
cout << calcWeeklyPay() << endl;
break;
Define you function : like
calcWeeklyPay(paramter1,parameter 2,paremeter3)
{
//do calculatioin and return ;
}
