here is the code:

 #include <iostream>
#include <queue>
#include <list>
using namespace std;

int main(void) {
    queue<int> q1;
    queue<int> q2;
   int i;
   while(i!= -999)
   {
       q1.push(i);
       cin >>i;
   }
    q2 = q1;

   cout << "Contents of q1:" ;
   while (!q1.empty()) {
      cout << q1.front() << "  ";
      q1.pop();
   }

   cout << endl;

   cout << "Contents of q2:" ;
   while (!q2.empty()) {
      cout << q2.front() << "  ";
      q2.pop();
   }

   return 0;
}

   int i;             // i doesn't yet have a value
   while(i!= -999)    // i could have any value at this point; let's guess it's not -999
   {
       q1.push(i);    // we haven't given i a value ... but let's put it in the queue anyway 

How about:

   int i;
   while( true )
   {
       cin >>i;
       if ( i == -999 ) break;
       q1.push(i);
   }

Thank you very much lastchance!!!!

Input could fail (those **** users ...). Therefore:

int i {};
while( cin >> i and i != -999 )
{
  q1.push( i );
}

Or you could keep it really short and sweet:
for (int i; cin >> i && i!= -999; ) q1.push(i);

@lastchance, it should be || instead of &&.

Are you sure?

I was for about 2 seconds.
WTF was I thinking???
