Problem 3: Operator Overloading Write a class Complex for complex numbers having the following data members: 1. Float a 2. Float b Write overloaded and default constructors for your class. Implement the following functionality for your class. float mag(); It will compute and return the magnitude of a complex number. The magnitude of a complex number a + bi is the quantity Vaz + b2 Complex add(Complex c); The method accepts a complex number c, adds it with this complex number and returns the answer as another complex number. The addition of two complex numbers, a+bi and C + di is defined as follows: (a + bi)+(c + di) = (a + b)+(c + d) The method accepts a complex number c, multiplies it with this complex number and returns the answer as another complex number. The multiplication of two complex numbers, a + bl and C + di is defined as follows: Complex mul(Complex c); [(a + b) (c + di) = (ac - bd) + (ad + bc)( Complex operator++; Overload pre-increment operator Complex operator++int); Overload post-increment operator Complex operator Overload pre-decrement operator Complex operator--(int); Overload post-decrement operator ostream& operator
