Answer:
A unique identifier for a wireless subscriber
Answer:
Explanation:
Transitive dependency
In this case, we have three fields, where field 2 depends on field 1, and field three depends on field 2.
For example:
Date of birth --> age --> vote
Partial dependency
It is a partial functional dependency if the removal of any attribute Y from X, and the dependency always is valid
For example:
Course and student these tables have a partial dependency, but if we have the field registration date, this date will depend on the course and student completely, we must create another table with the field registration date to remove this complete dependency.
If we remove or update the table registration date, neither course nor student must not change.
Answer:
customers += newCustomer;
Explanation:
The operator += expands into + and assignment. The assignment is not overloaded so the required code is
customers += newCustomer;
This expands into
customers = customers + newCustomer;
The overloaded + operator is called for the right expression. This returns a `CustomerList`, which is then assigned through the = operator to `customers`.
