(Math Review:) Will there be two roots for every choice of a
, b
, and c
?
No.
Let us consider roots that are real numbers, only. Then if:
Write a program that repeatedly asks the user for the coefficients a
, b
, and c
(which will be double precision)
and for each set writes out
Furthermore, write out an error message if a = 0
but continue processing.
If the user enters non-numeric data, the program will crash. (C can be more user-friendly than this, but the logic gets messy.)
What type of loop do you propose for this program?
