[Dev-C++] Char safeguarding

[Jay S. <mys...@op...>]

syntax
--------
    do{
        cout<<"Enter two positive integers. ";
        cin>>x>>y;
    }while(x<=3D0||y<=3D0);
--------

If I enter a char while using that, (x and y declared as ints), it gives =
me an endless loop.  How would I do safeguard against a user entering an =
char? -.-
