Write a program in C to simulate an elevator.

Guidelines:

The simulation is of people using the lift to arrive at their floor of a 8-story building. For the simulation we will expect people to start at floor 1 and exit at their destination. When all people have arrived at their floor, the simulation ends.

Passenger:

1) 10 people will use the elevator (1 thread per person created at the start of simulation).

2) Each person begins at floor 1 waiting for an elevator.

3) Each person randomly picks a floor from 2 to 8.

4) A person will wait for an elevator to arrive.

5) A person will enter into the elevator only if there is room.

6) A person will only board the elevator going to their floor.

7) Once at the destination floor, the person exits the elevator.

Elevator:

1) There is only 1 elevator (1 thread for this elevator).

2) Elevator can only hold 10 people.

3) The elevator starts on floor 1.

4) Elevator thread sleep 1 second per floor to simulate travel time.

Other Guidelines:

1) Each activity of each thread should be printed to the screen
