In C++, Queue and Deque are two distinct data structures with unique characteristics and purposes.<\/p>\n

    \n
  1. Line:<\/li>\n<\/ol>\n
      \n
    1. A queue is a data structure that follows the “First In, First Out” (FIFO) principle, much like waiting in line in real life.<\/li>\n
    2. You can only insert elements at the end of the queue and delete elements from the front.<\/li>\n
    3. There are only two operations: push (enqueue) and pop (dequeue).<\/li>\n
    4. In C++, a Queue is implemented using std::queue, with deque as the default container.<\/li>\n<\/ol>\n
        \n
      1. Double-ended queue:<\/li>\n<\/ol>\n
          \n
        1. A deque is a data structure with both queue and stack properties, allowing insertion and deletion operations at both ends.<\/li>\n
        2. You can insert and delete at both the front and end of the queue simultaneously.<\/li>\n
        3. Having more operations such as push_front (inserting at the front of the queue), push_back (inserting at the back of the queue), pop_front (deleting from the front of the queue), pop_back (deleting from the back of the queue), etc.<\/li>\n
        4. In C++, a Deque is implemented using std::deque.<\/li>\n<\/ol>\n

          Therefore, the main difference is that Deque is a data structure that has more operations and supports both queue and stack properties, while Queue only supports queue properties.<\/p>\n","protected":false},"excerpt":{"rendered":"
