The code must be C++, follows the criteria above, and outputs as follows:

a) Modify program from problem 1 such that it can produce real and complex solutions of quadratic equation. (25 points) Tip: C++ does not provide a special type for complex numbers, but you could use 4 double variables x1 Real, x2 Real, x1 Imaginary, x2 Imaginary. The first two variables will store the real part of the solution, and the other two-imaginary part. You could output the solution using this code: cout " X1= " x1 Real
