A quadratic() Function

Write a function called quadratic() that finds both roots of the quadratic equation. The main()

function prompts and inputs the values for a, b and c.

If a is zero, display an error message to cerr and return false. If the discriminant is negative, display an error message to cerr and return false. Otherwise, calculate the two roots and return true. The function prototype is

bool quadratic (double a, double b, double c, double & root1, double & root2);

Next write a main() function that inputs a trio of values for a, b and c. Then, main() calls

quadratic(). If there are roots, main() displays the two roots. Note that the only displaying that is done within the quadratic() function is to cerr for error messages.
