It's not standard, but you could try kbhit() (or _kbhit() or
__kbhit()!, depending on your compiler) which is in conio.h.

If it's in Windows then you could try checking GetAsyncKeyState()
during it iteration of the loop.

Code:

---

do
{
    if(kbhit())
    {
        keypress=_getch();
        if(keypress==13)
            break;
    }
}while(whatever);

I get an error when i input the code:

error C2065: 'keypress' : undeclared identifier
Error executing cl.exe.

do
{
cout << endl
<< "Enter employee last name: ";
cin >> lastname[count];

cout << endl
<< "Enter ssn: ";
cin >> ssn[count];

count++;
if(kbhit())
{

keypress=_getch();
if(keypress==13)
break;
}


} while (count < 50);

//Maximum employees is full
if (count == 50)
cout << endl << "Maximum employees for database is reached." << endl;


system ("CLS");

i was just making up a variable name. first you must declare it:

int keypress;

ok the program is executeable BUT
when i press enter nothing happens. it doesnt clear the screen & take me to the report screen?
