c++ - What is "operator<<" called? -

I know that most operators have names, but it is not certain that operator and operator & gt; & Gt; It is called .

i.e.

  operator = () // Assignment operator operator == () // equality comparison operator operator ++ () // increment operator operator - () // commission operator etc. operator & lt; () // At least the operator  

further ...

& lt; & Lt; left shift

& gt; & Gt; correct changes
