suppose i have declared :

queue<int> Q;

I want this Q empty at the beginning of each interation:

t=0;
while(t--)
{
//here I need the Queue empty

// here are oprations with that Q which may leave the queue un-empty at the end
}

what should I do to make my Q empty each time ??

Thanks in advance

You could also make your queue variable local to the while loop, since that seems to be the only place you use it.

Place the variable inside your while loop.

Code: Select all

t=10; 
while(t--) 
{ 
  queue<int> Q;        //here I need the Queue empty 

  // here are oprations with that Q which may leave the queue un-empty at the end 
}
