![]() The implementation of the queue can be branched into static implementation and dynamic implementation. This is considered to be FIFO or first in first out type of list. As an example, we may say that when the wrapper of biscuits is torn on one end, the biscuits can be taken out from there (popping) and from this end, biscuits can be put back (pushing). Pointers are used for implementing data structure with stack type. On the other hand, dynamic implementation is also known as linked list representation. Static implementation is not considered to have high efficiency associated with the utilization of memory. Though the static implementation is known to be effortless, it permits the declaration of the stack size only while designing the program after which the verification of size cannot be done. Stack in developed in static implementation with the help of arrays. Implementation of the stack can be done in two manners such as static implementation and dynamic implementation. There are several implementations of the stack such as undo in the word processor, java virtual machine, a compiler’s parsing, printers’ PostScript language, web browser’s back button, incorporating function calls in compilers, and others. It is known as the last-in-first-out type of list or LIFO due to this purpose. The last element added to the stack will be deleted as insertion or deletion is executed from the top of the stack. Examination of the full condition of the stack is Top = Max – 1.Įxamination of empty condition is Front = -1|| Front ++ Rear + 1 and examination of full condition is Rear = Max – 1. Examination of condition Examination of an empty condition associated with the stack is Top = – 1. ![]() Its implementation is comparatively complex. This data structure has variants such as priority queue, circular queue, and doubly ended queue. The implementation associated with it is simpler. Unlike queue, the stack data structure is not associated with variants. In the case of the queue, the rear end is concerned with the insertion and the front end is concerned with the deletion of elements. Structure In this data structure of stack, elements can be inserted with the utilization of one and can be deleted using the same end. The operations performed in this data structure are enqueue and dequeue. The number of pointers used in the queue is two. The operations performed in this data structure are push and pop. Usage of pointers and operations The number of pointers used in the stack is one. The working principle associated with the queue is considered to be first in first out list type or FIFO. Stack Queue Working principle The working principle associated with the stack is considered as LIFO or last in the first out type of list. Comparison Table Between Stack and Queue Parameters for comparison The queue can exhibit the performance of basic operations such as enqueue and dequeue. It has two ends rare and front ends where elements are inserted or deleted respectively. It is a gathering of elements that are similar to each other. The queue is also considered as the non-primitive type of data structure that is linear. The stack can exhibit the performance of basic operations such as PUSH and POP. From one end, the pre-established element is removed and new elements are added in this ordered list which is known as the TOS or the top of the stack. The stack can be described as a linear data structure that can be said non-primitive.
