It is also possible to make these types nullable, meaning that additionally to the usual values, null can be assigned, too. If a variable of a nullable type is not initialized, it will be null instead of 0. Nullable types are marked by adding a question mark (?) after the type.
int a; //This is now 0.
int? b; //This is now null.
