how does ofstream or ostream type cast all types to string?

Question

any system defined user type past to ostream object is converted to a string or char* ?

like cout<<4<<\"Hello World\";

works perfectly fine, how

Answer 1

is the << operator overloaded for each and every type?

yes

is there a way to achieve it through just one generic overloaded function?

this question doesn't make sense .. do you want just one function, or do you want an overloaded function?
