Try catch

[jackly84]

how do i place a try catch Statement into this ?


cout <<"Enter Student Number: ";
cin >> record[n].student_number ;

Making sure Student Number is only A Number ?

i cant get this to work
try
{
cout <<"Enter Student Number: ";
cin >> record[n].student_number ;
if(!(cin >=a))
}
catch
{
"Please Only Enter Numbers" << endl;
}

you don't need to use try - catch
check if the read of an integer works, if not clear the error, remove the faulty characters from the input stream and try again, e.g.

    int i;
    cout << " enter a number ? ";
    while (!(cin >> i))
       {
       cout << " Error _ enter a number ? ";
       cin.clear();             // clear error condition
       cin.ignore(1000,'\n');   // remove faulty characters
       }
