Which is the correct code that returns a complex number that is the complex conjugate of this one?
(a) Complex.prototype.conj = function() { return new Complex(this.r, -this.i); };
(b) Complex.prototype.conj = function() { return Complex(this.r, -this.i); };
(c) Complex.prototype.conj = function() { return (this.r, -this.i); };
(d) Complex.prototype.conj = function() { new Complex(this.r, -this.i); };
(a) Complex.prototype.conj = function() { return new Complex(this.r, -this.i); };
(b) Complex.prototype.conj = function() { return Complex(this.r, -this.i); };
(c) Complex.prototype.conj = function() { return (this.r, -this.i); };
(d) Complex.prototype.conj = function() { new Complex(this.r, -this.i); };
The correct answer is (a) Complex.prototype.conj = function() { return new Complex(this.r, -this.i); };
Explanation: Object.prototype.constructor specifies the function that creates the object prototype. The above code snippet returns a complex number that is the complex conjugate of this one.
