system crash when char is entered during int switch? solution?

i noticed when i have a switch statement the default does not catch chars...
here is a sample-

Code:

---

int input;
cin>>input;

switch(input)
{

case 1:
statement;
break;

case 2:
statement;
break;

case 3:
statement;
break;

default:
cout<<"cant do that\n";
break;

}

---

im guessing this is because the switch statement is only taking ints, but is there a way I can prevent a system crash if myself or someone accidentally inputs a char rather than an int?

Check with:

Code:

---

if (cin >> input)
