There are 4 main widely used stack operations.
Operations:
* POP - increase stack pointer and return top element * PUSH - putting element into stack's top * TOP - returns data of top element on stack * LENGTH/SIZE - returns number of elements inside stack For more detailed implementation details, please check web links.
yes
The top of a stack implemented as a linked list is the head of the list. All insertions and extractions occur at the head thus a forward list (singly-linked list) is sufficient to implement a stack.
Delete is mostly commonly known as pop in stack. The last element inserted into the stack is removed from the stack. Here is an illustration:Consider the stack with the elements 1,2,3,4 inserted in order.1->2->3->4\topThe top of the stack will be pointing to 4. When pop operation is performed, 4 is removed from the stack and the top is made to point to 3. The stack then becomes:1->2->3\top
Consider an array used as a stack. Align this array vertically. When an element is inserted into the stack, it is pushed all the way down despite the space availability at the top. Hence it is called push operation. Here's an illustration:Stack initially:|_||_||_||5|Stack after the insertion of 6:|_||_||6| - element pushed down as much as possible|5|
Push inserts a value onto the top of the stack. Pop extracts the top value from the stack. These are the two primary operations that can be performed upon a stack. Prior to popping a value, you will first check the stack is not empty, store the top value, then pop the stack. For a stack of type T, you might use the following: if (!stack.empty()) { T value {stack.top()}; // copy top value stack.pop(); // remove value from stack // use value... }
there are two operations you can do with a STACK one is PUSH operation and the other is POP operation
A stack can be implemented as an array or a list. If an array, simply push the new element onto the end of the array. If a list, point the new node at the head node then make the new node the new head of the list.
STACK operation in 8085 microprocessor.The stack is a reserved area of the memory in RAM where temporary information may be stored. An 8-bit stack pointer is used to hold the address of the most recent stack entry. This location which has the most recent entry is called as the top of the stack.When the information is written on the stack, the operation is called PUSH. When the information is read from the stack, the operation is called POP. The stack works on the principle of Last in First Out or Fist in Lat Out

int top=-1; int stack[10];

Something like this: before: #define MAXALLOC 256 after: #define MAXALLOC 512
Yes it is possible to implement stack and queue using linked list
