Hi Expert,

Having this piece of code:

while (...)
{
     cout << setw(16) << x;
}

Need the "x" to be printed at the same position at the window for all the iterations.

Can not find any flag/manipulator for that,
Can you help with this ?

TIA,
Oren.

I suppose you mean console, and not window?

Well, there would be specific methods for specific platforms, but on DOS/Windows you could try using the "backspace" character and output that to delete the previous value before writing the new one, something like (crude, could be improved, I s'pose):

char * del = new char[17];
memset(del,0x08,16);
del[16]=0;

Then:

while (...)
{
    cout << del;
    cout << setw(16) << x;
}
