Complex Numbers Calculator

This Complex class was a three-part solo project I completed in ICS 212, Fall 2024 using UH Unix. It takes user input for two complex numbers and performs arithmetic operations such as addition, subtraction, multiplication, and division, as well as equality and inequality checks. By implementing the Complex class, I gained the opportunity to strengthen my understanding of C++ syntax and object-oriented programming.

I encountered several key concepts in C++ during the implementation of the Complex class, most notably operator overloading and input/output streams that interact with the user.

As the programmer of the project, I was responsible for defining the Complex class and its member functions, ensuring that it could handle complex number computations. Here is a sample of the operations it supports:

---

 /**
   * ADDS the current Complex number to another
   * @param addComplex   the Complex object to be added to the current object
   * @return a new Complex object that represents the sum of the two complex numbers  
   */
  Complex add(const Complex &addComplex) const {
    // follows formula (a + bi) + (c + di) = (a + c) + (b + d)i
    double newReal = real + addComplex.real;
    double newImaginary = imaginary + addComplex.imaginary;

    // return a new object with above sums as parameters
    return Complex(newReal, newImaginary);
  }

  /**
   * SUBTRACTS another Complex object from the current one
   * @param subtractComplex   the Complex object to be subtracted from the current object
   * @return a new Complex object that represents the difference of the two complex numbers
   */
  Complex subtract(const Complex &subtractComplex) const {
    // follows formula (a + bi) - (c + di) = (a - c) + (b - d)i
    double newReal = real - subtractComplex.real;
    double newImaginary = imaginary - subtractComplex.imaginary;

    // return a new object with above differences as parameters
    return Complex(newReal, newImaginary);
  }
