exception handling problem here..

[jt1991]

hi how do i write an exception handling to handle a code where int = t2 and if i enter any input other than int for my t2, exception will come out.

heres my code and currently im am able to handle my value but not identifier (char, int)

    do
    {
     cout << "Cycle Time(in seconds, 15 - 20):";
     cin >> t2;
     if(t2 < 15 || t2 > 20)
     cout << "Invalid Input,(15 - 20 only), enter again\n";
    }while(t2 > 20 || t2 < 15);

i'm not quite sure why you want use an exception, but you should try to avoid them in regular cases.

If you're asking how to recover from a user entering non-digits when you're trying to read in an int:

do
{
     cout << "Cycle Time (in seconds, 15-20): " ;

     cin >> t2 ;

     if ( !cin ) // got some bad input!
     {
          cin.clear() ;   // reset state of cin.
          while (cin.get() != '\n')  // clear the input in the stream.
               ;
     }

} while (t2 > 20 || t2 < 15 ) ;

Exceptions wouldn't be appropriate in this case.
