Thread: problem with input

In the code below I want to only accept input of 1, 2, 3, 4, 5 or 6.

This works in that it will accept only one of those numbers and return it to my main.

If I enter a number such as '22' say, then it reprompts for a correct number; but if I input 'a' it locks the program up.

Is there a better way of asking for my input to stop this happening?

Code:

int menu ()
{
    int choice=0;

    cout<<endl<<"JayCee's Player Information Storage, Recall, and Amendment Facility"<<endl<<endl<<endl;
    cout<<"Please choose from :"<<endl<<endl<<endl;

    cout<<"       1  -  Ceate a new data file"<<endl<<endl;
    cout<<"       2  -  Add a record to an existing file"<<endl<<endl;
    cout<<"       3  -  Delete a record from a file"<<endl<<endl;
    cout<<"       4  -  Read a single record from a file"<<endl<<endl;
    cout<<"       5  -  Read whole file into an array"<<endl<<endl;
    cout<<"       6  -  End the program"<<endl<<endl<<endl;

    cout<<"                                 Choice  -  _\b";

    while  (choice<1 || choice>6)
        {
        cin>>choice;
        }

    return choice;
}
