Are temporary objects in C++ const indeed?

Question

I always believed that temporary objects in C++ are automatically considered as const by the compiler. But recently I experienced that the following example of code:

Answer 1

It all depends on the return type of the function.

//Temporary objects: nameless objects that are only usable in current statement
Object function();           //Return a temporary object by value (using copy constructor)
const Object function();     //Return a const temp object by value

//references, return a reference to an object existing somewhere else in memory
Object & function();         //Return an object reference, non-const behaves as any other non-const
const Object & functon();    //Return const obj reference, behaves as any other const
