    Code:
    #include <iomanip>
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
        int value = 1;
    
        // Should be "1"
        cout << value << endl;
    
        // Should be "0001"
        cout << setfill('0') << setw(4) << value << endl;
    
        // Alternate way to do above... don't need to use the iomanip header
        cout.fill('0');
        cout.width(4);
        cout << value << endl;
    
        return 0;
    }

    this is the line of code that I have put it into:

    Code:
    cout << setfill('0') << setw(4) << "\nID# for customer " << file[n].custname << " is " << file[n].custID << endl << endl;
    still doesn't seem to be working out...

    Rearrange it a little.
    Code:
    cout << "\nID# for customer " << file[n].custname << " is " << setfill('0') << setw(4) << file[n].custID << endl << endl;
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Try:

    Code:
    cout << "\nID# for customer " << file[n].custname << " is " 
         << setfill('0') << setw(4) << file[n].custID << endl << endl;
    The effect of the setw and setfill command disappear after the custname gets output so everything returns to "normal" (formatting-wise) by the time you output the custID. You should put the calls to them just before you output the value you need to have formatted like I have done above.

    I changed the line around to look like this now:
    Code:
    cout << "\nID# for customer " <<  setfill('0') << setw(4) << file[n].custname << " is " << file[n].custID << endl << endl;
    now it works like a charm, thnx for the help
