What are the stack and its operations? / What is the stack for example?

In this blog post(What are the stack and its operations), I am going to let you know about the stack and its function. A stack is one of the important data structures and comes in the category of non-primitive data structure.

Within this blog(What are the stack and its operations), we are going to share What is stack and its operations. What is the stack for example? What is the concept of stacks? What is stack in programming? Stack operations, Push operation in the stack, Application of stack.

A stack can also be known as an order list where the insertion of a new data item and deletion of an existing data item is done from one single end which is also known as TOS(top of stack).|What are the stack and its operations|

As we know stack allows insertion and deletion using one end such that the item inserted at last would be removed first and the item inserted at first would be removed at last.|What are the stack and its operations|

Because of this reason, the stack is given the name LIFO which is last in the first out type of list.

STACK

you would have seen plates over plates either at reception parties or in the office canteen where the top plate gets served first whenever it was kept at last and the last plate gets served at last though it was kept first.

You can relate many more real-life scenarios to match this stack operation.

The most accessible items are kept at the top and the least accessible items are kept at the bottom so that we can optimize the storage structure of the stack.

Whenever we add an item into the stack then we say we push the item into the stack and when we remove any item from the stack then we say…

… we pop it from the stack. So these were the technical terms used while we acted like using a stack.

The stack base remains fixed when it is created at first. And when a new element is added to the stack top goes on increasing,…

… and if we look the opposite when the top stack item is removed then the stack top goes on decreasing. See the below image to understand this scenario.

The basic stack operation:

There are a few basic operations that are used over the stack given below.

PUSH

This is the process in which a new element is added at the top of the stack. The top is incremented by one whenever a new element insertion takes place.

POP

This is the process of deleting or removing an element from the top of the stack. the top gets decremented by one when an element is removed from the stack top.

CREATE(s)

This operation is used to create an empty stack name as ‘s’

TOP(s)

This operation is used to return the top element of the stack s.

EMPTY(s)

This operation is to identify whether the stack is empty or not, and returns true if the stack is empty else false.

PEEP

If we want to extract any information stored at some location in the stack then we can use this operation for doing the same.

UPDATE

If we want to update the content at some location in the stack then we can use this operation update over a stack.

What is the use of the stack? When does it create?

A stack is noted but memory space is allocated when a program runs and thus the process is created. So once the process is created the memory is allocated.

A stack is used for storing the temporary data which may be some functions, local variables, and environment variables which helps us make communication or transition between the various functions.

This memory is generally created at compile time and is also known as static or compile-time memory.

Conclusion:

A stack is one of the types of memory allocation or management, this is the space that is allocated to the variables, and functions that are declared in the program. This is static memory and generally, gets free once the compilation process is done.
