why must you provide the keyword const in operator overloads
- by numerical25
Just curious on why a param has to be a const in operation overloading
CVector& CVector::operator= (const CVector& param)
{
x=param.x;
y=param.y;
return *this;
}
couldn't you have easily done something like this ??
CVector& CVector::operator= (CVector& param) //no const
{
x=param.x;
y=param.y;
return *this;
}
Isn't when something becomes a const, it is unchangeable for the remainder of the applications life ?? How does this differ in operation overloading ???
