hello,
so far I've been writing codes to take in numbers and make sure the input is within a given range, yet how can I use an array or a string to make sure the input the user has typed in is indeed an integer..
for example:
when the user types in "a" or " a 4" I want the program the ask for a new input.. but " 10 " or " +10 " is ok.
any ideas?
thanks in advance..
