[Dev-C++] C validating user input

[Dane E. <dg...@wo...>]

Hi all,

Using 'C' I need to prompt the user to enter an integer. Then I need to 
check if it is between 0-18.
What is the safest approach?


I tried:

int Num;
printf("Enter a value between 0 and 18: ");
scanf("%d", &Num);

if(Num > 0 && Num <= 18)...

but that makes the app go nuts if they enter: '.4' or something stupid 
like that.

Thank you in advance for any help you can offer.
