    Well, there are some things that will matter when you write this algorithm:
    - how many people will be in the hallway at once?
    - who walks the fastest/slowest?
    - how long does it take for these people to go from one room to another?
    - how many people can be in a room at once?
    Answer those questions and work out the algorithm from there.

    A Little Help

    Hello, I saw your post and prepared this code for you , it's not complete yet, but it is up to you to finish the simulation of the counting:

    Code:
    #include <iostream>
    #include <ctime>
    #include <cstdlib>
    
    #define _IN    200         //STATUS GOING IN
    #define _OUT   201        //STATUS GOING OUT
    #define _STAY  300        //STATUS ON THE ROOM
    
    using namespace std;
    
    const int iPeople = 100;        //# of People
    const int iSTAYallowed  = 75;       //Max allowed to STAY
    
    void Start();			//Initialize Random Speeds
    void Simulation(void);        //Simulation
    void Update();		         //Update to the Display
    
    struct Person			//The person(s)
    {
    	int speed;
    	int status;
    }People[iPeople];
    
    struct _Display			//Update Status
    {
    	int iPeoIn;
    	int iPeoOut;
    	int iPeoStay;
    }Display;
    
    
    
    int main()
    {
    	Start();
    
    	cout<<"\nPress [Enter] to start Simulation\n"<<endl;
    
    	cin.get();
    
    	Simulation();
    
    	system("PAUSE");
    	return 0; //or exit(0);
    }
    
    void Simulation(void)
    {
    	/*
    
        CODE HERE:
    		
    	*/
    }
    
    void inline Update()
    {
    	int in =0,
    		out=0,
    		stay=0;
    
    	for(int x=0; x<=iPeople; x++)
    	{
    		if(People[x].status == _OUT)
    		{
    			out++;
    		}
    
    		if(People[x].status == _IN)
    		{
    			in++;
    		}
    
    		if(People[x].status == _STAY)
    		{
    			stay++;
    		}
    		
    		Display.iPeoIn = in;
    		Display.iPeoOut = out;
    		Display.iPeoStay = stay;
    	}
    }
    
    void Start()
    {
    	srand( (unsigned) time(NULL) );         //Random Seed
    
    	for(int x=0; x<=iPeople; x++)          //Assinging Speeds and Status
    	{
    		People[x].speed = rand()%5000;
    		People[x].status = _OUT;
    	}
    }
    I already declared almost everything that you need, hope it helps
