A function pointer is a type of pointer in C, C++ and other
C-like programming languages. When dereferenced, a function
pointer invokes a function, passing it zero or more
arguments just like a normal function. In programming

code, such as replacing large switch statements.

The airport can accommodate 10 flights waiting for take-off at any point in time. Each flight has a unique 3 digit numeric identifier.  Each time a flight takes-off, Air Traffic Control adds a flight to the waitlist. Each time a flight is added to the waitlist, the list of flights waiting to take-off must be displayed.  When a flight is cleared for take-off, Air Traffic Control removes the flight from the waitlist.
