Close. If you declare myApp::foo as static, then you do not need 
to pass the pointer. Anything in your app can have access to it


A safer C++ way is to make myApp::foo private , then provide
public interface functions like string myApp::getfoo() const, 
and void myApp::setfoo(const string&) for reading and manipulating the
data. That way in your interfaces you can catch nastys like clients 
overflowing your string, or writing stupid data and such.
