(C++) What's the difference between these overloaded operator functions?
- by cv3000
What is the difference between these two ways of overloading the != operator below. Which is consider better?
Class Test
{
...//
private:
int iTest
public:
BOOL operator==(const &Test test) const;
BOOL operator!=(const &Test test) const;
}
BOOL operator==(const &Test test) const
{
return (iTest == test.iTest);
}
//overload function 1
BOOL Test::operator!=(const &Test test) const
{
return !operator==(test);
}
//overload function 2
BOOL Test::operator!=(const &Test test) const
{
return (iTest != test.iTest);
}
I've just recently seen function 1's syntax for calling a sibling operator function and wonder if writing it that way provides any benefits.
