operator overloading error
Code:
#include <iostream>
using std::cout;
using std::endl;
class CEstimatedInteger
{
private:
int value;
bool estimated;
public:
// Constructor
CEstimatedInteger(int val = 0, bool est = false) : value(val), estimated(est) { }
// Function to print value and estimation flag
void Print()
{
if (estimated)
cout << 'E';
cout << value;
}
// Addition operator for operands CEstimatedInteger + int
CEstimatedInteger operator+(const int& n)
{
return CEstimatedInteger(value + n, estimated);
}
// Addition operator for operands CEstimatedInteger + CEstimatedInteger
CEstimatedInteger operator+(const CEstimatedInteger& n)
{
return CEstimatedInteger(value + n.value, estimated || n.estimated);
}
};
CEstimatedInteger operator+(const int& a, const CEstimatedInteger& b)
{
return b + a;
}
int main()
{
CEstimatedInteger a;
return EXIT_SUCCESS;
}
Whats wrong with the above code?
I'm getting the following errors while compiling in Visual Studio 2008
