C++ const in getter

Question

I\'m still learning about C++ and I\'m reading everywhere that I have to use const everywhere I can (for speed reason I think).

I\'m usually write my getter

Answer 1

A const getter has the signature

bool getReady() const

The other version isn't a const method, it just returns a const value (which is basically useless).

Having a const getter allows you to call it on const objects:

const Object obj;
obj.getReady();

This is only valid if getReady is marked as const.
