Following is the source code for a Toll Bridge simulation program. Download the ADT Queue and save it as queue.h for the following code to work

#include <iostream.h>
#include <stdlib.h>
#include "queue.h"
static const int M = 4;
int main(int argc, char *argv[])
{
         int N = atoi(argv[1]);
         QUEUE<int>queues[M];
         for(int i=0; i<N; i++, cout<<endl)
         {
         int in = rand()%M, out = rand()%M;
         queues[in].put(i);
         cout<<i<<"in";
         if(!queues[out].empty())
         cout<<queues[out].get()<<"out";
         cout<<endl;
         for(int k = 0; k<M; k++, cout<<endl)
         { QUEUE<int>q=queues[k];
         cout<<k<<";";           
         while(!q.empty())
         cout<<q.get()<<" ";
         }
         }
}
