Write the following do-while statement with a while construct, and maybe some extra code.

```
x = 10;
do
{
cout << x << endl;
x = x - 3;
} while ( x > 0 );
```

A simple minded change from do while to while and insertion of the loop body gives this:
```
x = 10;
cout << x << endl;
x = x - 3;
while ( x > 0 )
{
cout << x << endl;
x = x - 3;
}
```

A look at the code suggests that the following is somehow 'smarter'
```
x = 10;
while ( x > 0 )
{
cout << x << endl;
x = x - 3;
}
```
