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
