Thread: Check for an integer, fail if anything else

I'm working on an integration program, that works out the integation by approximating with the rectangle rule.

I am trying to ask how many strips do you want? This MUST be an integer, yet if i enter a float, it will work. Is there a way of checking? i have looked but it seems that this integer check business is not as simple a check as it could be.

just need some code that will say

Code:

********* code*********

cout << "Please enter the number of strips:  ";
cin >> n; 

is n an integer?

       no - please retry

yes, carry on........
