Still working on a program and have searched the internet for various ways to test to see if input (DOS) is numeric. I see there are numerous ways and not sure how to proceed.
Values must remain as DOUBLE. Want user to have to re-input a value if they enter any non-numeric input. I guess they could enter positive and negative numbers as well as decimal. Need warning message if value is not numeric. Am using Dev C++ compiler
Thanks for the help
