Hey everyone! Would someone please tell me why this doesn''t work the way I think it should?
because you initilise the const in the initilisir list of the contructor its, valid, that s the only place you CAN initilise the const member, if you were to move that initilisation anywhere else it wouldnt work (like inside the ctor)
The non static const means const within the instance, but it may have different values for different instances. To accomplish this, you must have to set it once when constructing the instance.
.
You''re not modifying the const, you''re creating a *new* const which you initialize to a different value. Add
cout << x.foo << endl;
before program exit and behold that x.foo is still true while y.foo is false.
cout << x.foo << endl;
before program exit and behold that x.foo is still true while y.foo is false.
