How to make a Switch Exit

A Switch.

How do I make it that if someone enters anything else other that an integer (1,2,3 or 4) into this switch, that the program then displays a message "Try again" and then displays the menu over again for them to choose from.

At the moment whenever I enter an non integer value it loops constantly, with the default value displaying.

int chioce;
do
{
cin >> choice;

switch (choice)
{
case 1:
flag=true;
break;
case 2:
flag=true;
break;
case 3:
flag=true;
break;
case 4:
flag=true;
break
default:
cout << "Not a Valid Choice" << endl;
}while (flag !=true);

Thanks

default:
cout << "Not a Valid Choice" << endl;
cin.clear ();
cin.ignore (INT_MAX, '\n');

for INT_MAX include limits.h

Where do you set 'flag' to false?

int chioce;
do
{
cin >> choice;
flag = false; // <-- i miss this here

switch (choice)
{
case 1:
flag=true;
break;
case 2:
flag=true;
break;
case 3:
flag=true;
break;
case 4:
flag=true;
break
default:
cout << "Not a Valid Choice" << endl;
}while (flag !=true);
