Declaration inside the class: Integer operator+ (const Integer& right); Definition outside the class: Integer

  • 0

Declaration inside the class:
Integer operator+ (const Integer& right);

Definition outside the class: 

Integer operator+ (const Integer& left, const Integer& right)
{
    return left ;
}

What sense does it make for the compiler to enforce different number arguments in declaration and definition?

    You declared two different operator+ there. The correct out-of-class definition would be this:

    Integer Integer::operator+(const Integer& right)
{
    return *this;
}
