It's hard to know what you're asking, especially as your code
doesn't compile.

When you have an expression like

   cout << foo;

then the function that is called depends on the type of 'foo'.
For many types, the C++ Standard specifies what the output
should be (and what other effects, if any, occur).  For other
types you can define your own operator<< to do whatever you like.
