Question

Could anyone help me with this C++ task: I need to read numbers that are being entered separated by spaces and store them into an array. At the same time, I have to filter out non-numbers entered, expect 'x' which is the sentinel value. I am having a brain block on how to achieve this. Thank you for any help.

Answer 1

Isn't there a Scanner class to break the string down? I think the String class has conversion methods.

Answer 2

<cctype> should have an isdigit function
you can also write your own, but that'd be pointless.

Answer 3

cin to get the numbers and then store them in an array. and yes isdigit is available of course.
