4,075 PointsCan you further explain why you have named a method 'to_s'?
I thought that this was a standard Ruby method and we shouldn't be overwriting them? Also, you never call the to_s method when you type:
puts bank_account
So how does the program know to run that?

There's nothing wrong with overriding standard behavior if it lets you write your desired program more easily. That the language doesn't try to stop you is a hint that it's okay.
So how does the program know to run that?
puts
knows how to check whether or not the value you pass is a string. It also knows that to_s
is a standard Ruby method, and will use that to figure out how to turn bank_account
into a string.
