If I change it to void setOutputFormat(ostream& out, int decimal_places),
with a call by reference, it works. I don’t understand why though?
What is the difference between a struct and a class, besides struct members are by default public, and class members are by default private?
You’re right that there is no difference between class and struct, except the default private vs private.
The problem here is that ostream doesn’t have a copy constructor, so you can’t pass it by value.
