C++ Format for cout << Automatically -

-

if had simple class 2 variables, x , y, , function tostring() returns formatted string data. when call 

cout << simpleclass << "\n";

anyone know way have simpleclass.tostring automatically called return correctly formatted string? i'm guessing there's way operator functions, don't know how this.

if you're asking how define such operator,

template<class chart, class traitst> std::basic_ostream<chart, traitst>& operator <<(std::basic_ostream<chart, traitst>& os, simpleclass const& sc) {     return os << sc.tostring(); }
