c++ operator overloading not equal code example
Example: c++ operator overloading not equal
lass Fred {
public:
// ...
};
if
// Without operator overloading:
Fred add(const Fred& x, const Fred& y);
Fred mul(const Fred& x, const Fred& y);
Fred f(const Fred& a, const Fred& b, const Fred& c)
{
return add(add(mul(a,b), mul(b,c)), mul(c,a)); // Yuk...
}
else
// With operator overloading:
Fred operator+ (const Fred& x, const Fred& y);
Fred operator* (const Fred& x, const Fred& y);
Fred f(const Fred& a, const Fred& b, const Fred& c)
{
return a*b + b*c + c*a;
}
