Answer / susie

Answer : & Explanation:

The second one is better because gets(inputString) doesn't
know the size of the string passed and so, if a very big
input (here, more than 100 chars) the charactes will be
written past the input string. When fgets is used with stdin
performs the same operation as gets but is safe.
