(C++) operator<<

operator<< (pronounced as 'stream out operator') is an operator to sending data to a stream. Use operator>> to read data from a stream.

Examples

• Hello World
• operator << example 1: overloading

Advice

• Prefer overloading operator<< with a free function [1]
• Note to self: prefer overloading operator<< over a 'ToStr' member function, because a stream can be more flexibly manipulated (consider streaming a std::setprecision before streaming a class instance
