The implementation of queue using array concludes with a versatile technique that simplifies data management. This approach, based on first-in, first-out processing, provides a useful tool for organizing and optimizing data flow. Array-based queues strike a balance between simplicity and efficacy, im...
using namespace std; // Define the default capacity of the queue #define SIZE 10 // A class to represent a queue template <class X> class queue { X *arr; // array to store queue elements int capacity; // maximum capacity of the queue int front; // front points to the front eleme...
return0; } In the above implementation, to show that the queue is empty, bothrearandfrontindices are set to(-1). The execution starts from themain()function whereenqueue()function inserts a component to thequeue’srear by increasing therearindex while setting thequeuearray’s value at the ...

A Queue can be implemented in many ways using arrays,linked lists, Pointers and Structures. But for some simplicity’s sake, we should implement it using the single-dimensional or one-dimensional array. Before going into detail, we should have prior knowledge of when to use the current data ...
The complexity of enqueue and dequeue operations in a queue using an array is O(1). If you use pop(N) in python code, then the complexity might be O(n) depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling When data is transferred ...
Q5. Can a queue be implemented using an array? Yes, a queue can be implemented using an array. In such an implementation, the rear of the queue is associated with the end of the array, and the front is associated with the beginning. However, it is important to handle cases of overflow...
Size: Returns the total number of elements present in the queue. Practice this problem Queue Implementation using an array: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48...
In Array implementation FRONT pointer initialized with 0 and REAR initialized with -1.Consider the implementation :- If there is 5 items in a QueueNote: In case of empty queue, front is one position ahead of rear : FRONT = REAR + 1;...
Using Array:To implement a queue in C using an array, first define the queue's maximum size and declare an array of that size. The front and back integers were respectively set to 1. The front variable represents the front element of the queue, and the back variable represents the back ...
