You need to convert to void * for the printing with iostreams, and you need a safe address-of operator that doesn’t get confused by overloaded &-operators. In other words:

std::cout << static_cast<void*>(std::addressof(text[0])) << std::endl;

You need <memory> and <iostream>, as well as a recent compiler.

Update: Note that this code gives you the static address of the operand. If you want to pass a base reference of a polymorphic object, you should use dynamic_cast<void*>(x) instead, but this works only for polymorphic objects (i.e. those with virtual functions), and it gives you the address of the actual, dynamic object.
