Question

Using C++, please use Selection Statements, Pointers, Functions and OOP only.

TEST CASE #1:
If the starting floor is 1 and destination floor is 5,
Program will display:
"2"
"3"
"4"
"now in level 5"
TEST CASE #2:
If the starting floor is 2 and destination floor is 2,
Program will display:
"start and destination floor is the same"

PROBLEM: Consider the elevator in the Faculty of Engineering (5 storex). Write a program which
accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The
passenger can then input the target destination floor.
SPECIFICATIONS:
Implement the class diagram below:
Elevator
- noLevels: int
+ Elevator(int _levels)
+goUp(int from, int to): void
+ goDown(int from, int to): void
Inside the main method, create an instance of the class Elevator. Use the goUp or goDown
methods to generate the program display.
Passenger can ride in any floor (1,2,3,4 or 5).
Program will prompt the user with the target destination floor. After the user input:
o Program will display the floors which the elevator passes through, and finally the
destination floor.
O
Elevator will not move if the input for destination floor is the same as the present floor.
Program will notify the user and then terminate.
o
Program will also terminate if the input destination is not 1,2,3,4 or 5.
You're free to format the input/output display.
