Operator<< for ostream

[Oliver Block]

Hi @ll,

I'am programming a class for big integer number. I needed one for
powers because int an long didn't fulfill my needs.

I coded some operators but now I am somehow lost. I store the digits
for my class in a valarray and I'd like to output them on cout for
example.

Is there a better way than to copy the digits to a String and return
the string?

I appreciate your hints!

bye,

Oliver

Re: Operator&lt;&lt ; for ostream

operator<< writes directly to output stream

class A {


friend ostream& operator<<(ostr eam& os, const A& a) {
os << ............... .
return os;
}
};
