Checking each character for a number

Question

I am trying to loop through a string and check each character if one of the characters is a number. If it is a number, I want to return it as true. I have a string \"crash\"

Answer 1

Maybe I didn't understand you correctly... but since you're using the same variable "isNumber", and continuing when you get a positive match... the result you'll return will always be of the last character of the String, except when you get a non numeric character, in which case, you exit right away.

Do you want to check if the whole String is a number? Or if it contains a number?
