This lab implements classes that may be used to simulate the operation of an elevator in a buildingas people request to move between floors. The classes use randomized numbers to determine the times that people arrive, which floor they want to go to, etc..-
In this lab you will write two classes and a main program that demonstrates the use of the classes. This lab does NOT include the complete simulation of the elevator., The building has ten floors, numbered 0..9. Each person will arrive at the building lobby, which is floor O. The person will have a definite floor that she wishes to visit for a definite amount of time.

1. Using documentation such as your textbook Ch. 3.9 and www.cplusplus.com, review C++ pseudo-random numberfunctions, especiallythe seed function...

2. Write a function named time Visiting that, • accepts two integer parameters, a and b. The range of a and b are 0 <= a b <= INT_MAX.. • returns a random integer uniformly distributed between a and b inclusive.. • (You will need to scale and shift the value returned by ranc10.),

3. Write a class named Persona • The class contains data members fore o time of arrival at the building o destination floor that the person will visit, uniformly distributed in the range 0..9. o time that the person will spend at the destination floor, uniformly distributed in a sensible range o time the person arrives back at the lobby to leave the building
