Stack underflow occurs when an operation is attempted on an empty stack, resulting in an attempt to access a nonexistent element at the top of the stack. This can lead to errors or unexpected behavior in programs that rely on stack data structures. To prevent stack underflow, it is important to check the stack's current size before performing operations that could potentially lead to underflow.

When will stack overflow and stack underflow condition occur insequential organization?
In a sequential organization, a stack overflow condition occurs when there is an attempt to push an element onto a stack that is already full, exceeding its allocated memory limit. Conversely, a stack underflow condition occurs when there is an attempt to pop an element from an empty stack, which has no elements to remove. Both conditions can lead to runtime errors and need to be handled to maintain the integrity of the stack operations. Proper checks should be implemented to prevent these situations.
What are overflow and underflow conditions in stack?
A stack overflow occurs when the on--chip stack capacity is exceeded. This can be detected by a comparison of the top-pointer, the last-pointer and the index specified for a create-frame operation ( for push). Initially the top-pointer is set to 1 and the last-pointer to 0, placing a dummy element on the stack.If an index specified for a read access is greater than the number of valid on--chip stack elements, a stack underflowoccursQueue overflow results from trying to add an element onto a full queue and queue underflow happens when trying to remove an element from an empty queue.
What is the meaning of popping in computer programming?
Popping is the opposite of pushing. You push values into a queue and pop them off. The queue is generally represented by a stack, where the last value pushed onto the stack is the first to be popped off the stack (last in first out, or LIFO).
What is implicit stack?
A stack created by the user or a programmer is an implicit stack
Where string is stored on Heap or Stack in java?
A String is treated as an object, meaning there is an object on the heap. Of course, the variable you define is a pointer to the object, and it is stored on the stack.A String is treated as an object, meaning there is an object on the heap.

Is stacked a noun?
No the word stacked is not a noun. It can be an adjective meaning arranged in a stack. It can also be a verb where it is the past tense of the verb to stack.
What is the meaning of stack-based buffer overflow?
A buffer overflow occurs when you put more stuff into it than it can hold. For a stack, it means you put or pushed onto the stack more information than the size of the stack.If I have a stack that can hold 10 entries, then putting 11 in the stack will overflow it.
What type of noun is stack?
The word "stack" is a common noun, referring to a pile or a collection of items arranged in a specific way. It can also be used as a verb, meaning to arrange items in a stack. In specific contexts, "stack" can be a collective noun when referring to a group of similar items, such as a "stack of books."

What are the important applications of stacks?
In computer science, a stack is an area of memory that holds all local variables and parameters used by any function, and remembers the order in which functions are called so that function returns occur correctly. Each time a function is called, its local variables and parameters are "pushed onto" the stack. When the function returns, these locals and parameters are "popped." Because of this, the size of a program's stack fluctuates constantly as the program is running, but it has some maximum size.One way of describing the stack is as a last in, first out (LIFO) abstract data type and linear data structure. A stack can have any abstract data type as anelement, but is characterized by two fundamental operations, called push and pop (or pull). The push operation adds a new item to the top of the stack, or initializes the stack if it is empty. If the stack is full and does not contain enough space to accept the given item, the stack is then considered to be in anoverflow state. The pop operation removes an item from the top of the stack. A pop either reveals previously concealed items, or results in an empty stack, but if the stack is empty then it goes into underflow state (It means no items are present in stack to be removed). A stack pointer is the register which holds the value of the stack. The stack pointer always points to the top value of the stack.A stack is a restricted data structure, because only a small number of operations are performed on it. The nature of the pop and push operations also means that stack elements have a natural order. Elements are removed from the stack in the reverse order to the order of their addition: therefore, the lower elements are those that have been on the stack the longest
What is the meaning of popping in computer programming?
Popping is the opposite of pushing. You push values into a queue and pop them off. The queue is generally represented by a stack, where the last value pushed onto the stack is the first to be popped off the stack (last in first out, or LIFO).
What is the meaning of a stack overflow?
A stack overflow is a programming term used to identify when a function tries to access memory from a stack that does not exist. A stack, such as a queue or array, contains a limited number of memory spaces set aside when it is created. For example, if an array has 8 objects in it and a function tried to access an item at slot nine, which doesn't exist, it would cause a stack overflow.
