basic input

i have this code:

Code:

---

cout<<"level number:";
cin>>levnum;

---

it goes it loops of itself if u input wildcards or chars
how would i stop it doing this ie return an error saying incorrect levnum?:D

Read a string instead of whatever levnum is now and validate it by checking the length of the string and that each element matches a digit and that the number is within your range for levels, then convert it to an integer with atoi.

-Prelude

After you get the input do this:

#include <ctype.h>

if(isdigit(levelnum))
{
// Is a digit
}
else
{
cout << "Must be digit!";
}
