Good evening S.O!
Whats the problem?
So I'm trying out a few test examples in of class creation and constructors, and I'm trying to overload a constructor by passing it different parameters. In the following code, I overload Sale by using parameters (double rate) and ().
From my limited knowledge about overloading, this should work. Only problem.. it doesn't seem to.
Here's some code
#include "stdafx.h" // Defines IDE required "pre-compiled" definition files
#include <iostream> // Defines objects and classes used for stream I/O
#include <iomanip>
//Namespaces utilized in this program
using namespace std;
// Announces to the compiler that members of the namespace
// sale class declaration
class Sale
{
private:
double taxRate;
public:
Sale(double rate) //Constructor with 1 parameter, handles taxable sales
{
taxRate = rate;
}
Sale()
{
taxRate = 0.0; // handles tax-exempt sales
}
double calcSaleTotal(double cost)
{
double total = cost + cost*taxRate;
return total;
}
};
int main()
{
// Constant "const" Value Declarations
const int NO_ERRORS = 0; // Program Execution Status: No errors
// Initialized Variable Declarations
int programStatus = NO_ERRORS; // Assume no program execution errors
Sale cashier1(.06); //defines a Sale object with a 6% sales tax
Sale cashier2(); // define a tax-exempt Sale object
//format the output
cout << fixed << showpoint << setprecision(2);
//Get and display the total sale pricefor two 24.95 sales.
cout << "With a 0.06 sales tax rate, the total\n";
cout << "of the $24.95 sale is $";
cout << cashier1.calcSaleTotal(24.95) << endl;
cout << "\nOn a tax-exempt purchase, the total of the $24.95 sale is, of course, $";
cout << cashier2.calcSaleTotal(24.95) << endl;
// This prevents the Console Window from closing during debug mode using
// the Visual Studio IDE.
// Note: Generally, you should not remove this code
cin.ignore(cin.rdbuf()->in_avail());
cout << "\nPress only the 'Enter' key to exit program: ";
cin.get();
return programStatus;
As you can see
I've defined two class objects, both Sale cashier1(.06) for my taxable purchases and
Sale cashier2() for my tax-exempt purchase.
My cashier1 is defined as a Sale class no problem and runs fine. cashier2 however gets an error saying that expression must have a class type.
Where in my code did I go wrong?
Thanks in advance :D Happy coding!
