Character handling problem! (isdigit)

[dexter1984]

void choiceSelect()
{
    int choice;
    char exitconfirm[100];
    printmenu();
    cin >> choice;

    if (isdigit(choice))
    {
        if (choice == 7)
        {
            cout << "Exiting program. Enter yes to confirm.\n";
            cin.ignore();
            cin.getline (exitconfirm, 100, '\n');
            if (strcmp ("yes", exitconfirm) == 0)
            {
                exit (1);            
            }

Hi, I need some help with my assignment yet again. This time, it's just a simple recursive loop that I can't get working.

I've done most parts but I can't figure out why the "isdigit" isn't working. I want the program to detect if the user inputs anything other than numbers.

If I understand correctly,
if (isdigit(choice))
if choice = numbers, it'll run the program since it's true. However, it doesn't, Instead it runs the else part.

Can anyone point me in the right direction. Appreciate the help:$

Doesn't isdigit expect a char?

Aaaa I see, forgot about the little int choice at the top.
Thanks!
